This page provides the simplest online calculator for calculating the volume of a room. With this one-click calculator, you can calculate the volume of a room if you know the length, width and height.
A square meter is a unit of area, equal to the area of a square with a side length of 1 meter. A cubic meter is a unit of volume, equal to the volume of a cube with ribs of 1 meter. Thus, these units are used to measure various properties of matter, therefore, from the point of view of physics, it is not entirely correct to talk about translating one unit of measurement into another.
However, in practice, there are often situations when it is necessary to convert dissimilar units of measurement (for example, a square meter to a cubic meter and vice versa).

Converting square meters to cubic
Most often, such a conversion is useful when calculating the amount of building materials, since some of them are sold in cubic meters, and are intended for arranging various surfaces that are conveniently measured in square meters. In order to convert square meters to cubic meters, in addition to the length and width of the product, you need to know its thickness. Product volume is calculated by the formula V=a*b*c, where
- a,b and c - length, width and height in meters.
For example, you need to sheathe a room with clapboard.
How to calculate the volume in m3?
The total area of the walls is 200 square meters. The lining is sold in cubic meters. The lining thickness is 1 cm. In order to calculate the volume of building materials, the following calculations must be made:
- Now you need to multiply the area of \u200b\u200bthe walls by the thickness of the lining in meters: 200 * 0.01 \u003d 2 cubic meters.
Thus, in order to sheathe 200 meters of square walls, you will need 2 meters of cubic lining.
Convert cubic meters to square meters
In some cases, it may be necessary to convert cubic meters to square meters - that is, to measure how many square meters of material are contained in one cubic meter. To do this, you need to know the volume and thickness (height) of the material and make calculations using the formula: S = V / a, where:
- S - area in square meters;
- V - volume in cubic meters;
- a - thickness (height) of the material.
Thus, if you need to determine what area can be sheathed with 1 cubic meter of lining 1 cm thick, you need:
- Convert the thickness of the lining in centimeters to meters: 1/100 \u003d 0.01 meters;
- Divide the volume of lining in cubic meters by the resulting thickness in meters: 1 m3 / 0.01m = 100 m2.
Thus, with a clapboard, the volume of which is 1 cubic meter, it is possible to sheathe walls with an area of 100 square meters.
In order for these calculations not to seem so complicated, it is enough to visualize the concepts of a cubic meter and a square meter. So, to imagine 1 cubic meter, you need to mentally draw a cube, the sides of which are equal to 1 meter.
To imagine how many square meters are contained in one cubic, you can divide the vertical plane of the cube into conditional strips, the width of which is equal to the thickness of the material being represented. The number of such bands will be equal to the area of the material.

How to find volume in terms of areaVolume - a measure of capacity, expressed for geometric shapes in the form of the formula V=l*b*h. Where l is the length, b is the width, h is the height of the object. In the presence of only one or two characteristics, it is impossible to calculate the volume in most cases. However, under certain conditions it seems possible to do this through the area. Instruction

Volume is a geometric term that allows you to measure the quantitative characteristics of residential and non-residential space.
It is possible to determine the volume of a room, having information about its linear dimensions and shape characteristics. Volume is very closely intertwined with capacity characteristics. Surely everyone is familiar with such terms as the internal volume of a vessel or any container.
The volume unit is classified according to worldwide standards. There is a special measurement system - SI, according to which a cubic meter, liter or centimeter is a metric unit of volume.
Any room, whether it is a living room or a production room, has its own volume characteristics. If we consider any room in terms of geometry, then the room is comparable to a parallelepiped. This is a hexagonal figure, in the case of a room, its edges are the walls, floor and ceiling. Each side of the room is a rectangle. As is known from geometry, there is a formula for finding the volume of a rectangular parallelepiped. The volume of this figure is calculated by multiplying the three main dimensions of the parallelepiped - the length, width and height of the faces. You can also calculate the volume of a room using a simpler formula - the floor area is multiplied by the height of the room.
How to find out the volume of a room
So, how do you calculate the volume of a particular room? First, we measure the length of the wall, the longest in the room. Then we determine the length of the shortest wall in the room. All these measurements are carried out at the floor level, along the line of the baseboards. When measuring, the tape measure must be level. The time has come to measure the height of the ceiling. To do this, you need to hold a tape measure from floor to ceiling in one of the corners of the room.
All measurements must be recorded to the nearest tenth. After that, you can proceed directly to the calculation of the volume of the room. We take the length of the largest wall, multiply it by the length of the smallest wall, then multiply the result by the height of the room. As a result, we get the necessary numbers - the volume of the room.
It is necessary to calculate the volume of a room in a variety of situations. So, you need to know the volume of the room when installing a sectional heating radiator. The number of sections in it directly depends on the volume of the room. If you are installing an air conditioner, you also need to know the volumes of the room, since a separate air conditioner is designed only for a specific volume of the room.
Complex room volume
In the case when the room has an irregular shape, you need to start again from the figure of a parallelepiped. In this case, the room will be represented by a large and small volumetric body. So, the volume must be measured separately for a large parallelepiped, and then for a small one. After that, the two volumes are added together. It happens that the structure of the room is completely non-standard, there may be arches and niches of a semicircular formation. In this case, the volumes must be calculated using a different formula - the volume of the cylinder. The volume of a cylinder is always calculated according to a single formula - the area of \u200b\u200bits base is multiplied by the height of a cylindrical body. Semicircular structures in the room can be represented as part of a cylinder, based on this, calculations are made of the total volume of the cylinder, and then the excess part is subtracted from them, in accordance with the dimensions of the semicircular niche.
How to find the volume of a room
Estimation of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as to select an effective heating or air conditioning system. Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.
2. If the room has an irregular or complex shape, the task becomes a little more complicated. Break the area of the room into several simple figures and calculate the area of \u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.
5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements of the structure. Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful.
Room volume formula
How to calculate the volume of a room
Volume is a quantitative feature of a place. The volume of the room is determined by its shape and linear dimensions. The concept of capacity is closely intertwined with the concept of volume, in other words, the volume of the internal space of a vessel, packing box, etc. The accepted units of measurement are in the SI measurement system and its derivatives - cubic meter m3, cubic centimeter, liter. You will need To measure the volume of a room, you will need a tape measure, a sheet of paper, a calculator, a pen. 1 Each room, for example a room, is, from a geometric point of view, a rectangular parallelepiped.
A parallelepiped is a large figure with 6 faces. and it doesn't matter which of them is a rectangle. The formula for finding the volume of a rectangular parallelepiped is: V=abc. The number of a rectangular parallelepiped is equal to the product of 3 of its dimensions. Apart from this formula, you can measure the amount of space by multiplying the floor area by the height.
2 So start calculating the volume of the room. Determine the length of one wall, later determine the length of the 2nd wall. Take measurements on the floor, at the level of the plinth. Keep the tape measure straight.
At the moment, determine the height of the room, to do this, go to one of its corners, and accurately measure the height along the corner from floor to ceiling. Write down the acquired data on a piece of paper so as not to forget.
How to calculate the volume in m3 of concrete calculator
At the moment, proceed to the calculations: multiply the length of a long wall by the length of a short wall, multiply the acquired product by the height and you will get the required result.
The volumes of rooms are calculated in various cases: 1) in the case of purchasing an air conditioner, since air conditioners are designed for a certain number of rooms; 2) with the case of installing heating radiators in rooms, since the number of sections in the radiator depends on the volume of the room. 3 If you have an irregularly shaped room, in other words, it consists of a seemingly huge parallelepiped and a small one. In this case, it is necessary to measure the number of each of them separately, and then add them up. If your room has an alcove. then its amount must be calculated using the formula for the volume of a cylinder. The number of any cylinder is equal to the product of the area of the base and the height: V \u003d? r2 h, where. is the number "pi" equal to 3.14, r2 is the square of the radius of the cylinder, h is the height.
Imagine your alcove for yourself as part of a cylinder, calculate the amount of what seems to be the entire cylinder, later look at what part of this cylinder your alcove occupies, subtract the excess part from the total volume.
How to calculate the area of a room?
If a room has four walls and has a standard geometric figure with right angles, then it is necessary to measure two walls and multiplying the resulting two numbers by each other we get the area of the room, and for the volume you need to multiply the result by the height. but this is only with regular geometric shapes.
It is more difficult to find the area and dimensions when the shape of the room is the wrong size, for example.
Then you need to apply all the knowledge of geometry, namely, divide the room into several regular figures and, in accordance with the formulas of these figures, find their area, and then add all the results together, then you get the total area of \u200b\u200bthe room. To find the height, you need to multiply the result of the total area by the height.
Things are even worse with non-standard rooms with irregular wall and roof angles. Then you have to transfer all the dimensions of the room to paper, divide it into regular figures and, based on each figure, find its area and volume, and then summarize the results.
The area of the room does not include protrusions of windows and other things that are higher than the floor, but they are included in the calculation of the volume of the room.
How to calculate the area of a room
In the case of measuring an irregularly shaped room, for a more accurate calculation of the area, it is recommended to divide it into rectangles. By calculating the area of \u200b\u200beach such area, you can find out the total area of \u200b\u200bthe room by simply summing up all the results obtained.
If it is not possible to divide the room into rectangular sections, then you can try such shapes as a triangle or a sector of a circle. The area of a triangle is calculated using Heron's formula: S=v**).
P - half-perimeter of a triangle, which can be calculated in this way: p \u003d / 2

Calculation of a brick for a house: an online calculator and how to check the calculations manually
Estimation of the volume of premises is quite often required in the production of construction and repair work. In most cases, this is required to clarify the amount of materials needed for repairs, as well as to select an effective heating or air conditioning system.
Quantitative characteristics describing space, as a rule, require some measurements and simple calculations.
1. The simplest case is when it is required to determine the volume of a room of a regular rectangular or square shape. Using a tape measure, measure in meters the length and width of the walls, as well as the height of the room. It is most convenient to take measurements along the floor, along the baseboards. Multiply the obtained indicators of length, width, height and you will get the desired volume.
2. If the room has an irregular or complex shape, the task becomes a little more complicated. Break the area of the room into several simple shapes (rectangles, squares, semicircles, and so on) and calculate the area of \u200b\u200beach of them, having previously made measurements. Add up the resulting values, summing the area. Multiply the amount by the height of the room. Measurements must be carried out in the same units, for example, in meters.
3. When carrying out construction work, the determination of the volume of the entire structure is determined by the standards. The so-called building volume of the ground part of the building with an attic can be calculated by multiplying the horizontal sectional area along the outer contours at the level of the lower floor. Measure the full height of the building from finished floor level to the top of the attic insulation. Multiply both numbers.
4. If there are floors of different sizes, determine the total volume of premises in the building by adding the volumes of all parts. In the same way, the volume is determined if the premises have different outlines and designs.
5. Separately calculate the volumes of verandas, bay windows, vestibules and other auxiliary elements of the structure (with the exception of covered and open balconies). Include this data in the total volume of all rooms in the building. Thus, you can easily find the volume of any room or building, the calculations are quite simple, try and be careful. 
2.4 Calculation of the capacity of public buildings and the size of their land plots
Public buildings house institutions and public service enterprises.
By specialization and types of services, public institutions and enterprises are divided into preschool (nurseries and kindergartens), schools, health care, cultural and educational, public utilities, trade and distribution, public catering, administrative and economic, etc.
Calculation of the volume of the room.
The composition of public institutions for each populated area is initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. This takes into account the possibility of further operation of existing buildings.
The calculation of the capacity or throughput of institutions and service enterprises is carried out according to the design norms (SNiP).

2.5 Drawing up a list of design buildings and structures
Public buildings house institutions and public service enterprises. By specialization and types of services, public institutions and enterprises are divided into:
Preschool children's (nurseries and kindergartens);
school;
healthcare,
cultural and educational;
· household;
· trade and distribution;
· Catering;
Administrative and economic and others.
According to the territorial coverage of services, they can be divided into the following groups:
1) servicing residents of several settlements;
2) services for residents of one populated area;
3) services for residents of certain parts of a populated area.
The first group includes institutions located in regional centers and serving the entire population of the region (district Council of People's Deputies, House of Culture, post office, department store, etc.), as well as institutions serving a group of settlements and located in the largest of them, for example , in the central estates of farms (village Council of People's Deputies, state farm office, collective farm board, secondary school, hospital, etc.). The second group consists of institutions serving all residents of one populated area. The third group includes institutions that serve residents of certain parts of a large populated area and are represented in it by several buildings located at different points (kindergartens and nurseries, schools, grocery stores, etc.).
This system of service establishments was called the "step system". It ensures the proximity of service establishments to residents. Thus, the first group includes institutions of episodic use, the second - periodic use, and the third - provides for daily maintenance.
The composition of public institutions for each populated area is initially developed in the draft district planning, which presents the entire system of resettlement in the area and the placement of institutions and service enterprises in settlements. These developments are taken into account when determining the composition of public buildings in a particular populated area. At the same time, the possibilities of further operation of existing public buildings are taken into account.
The calculation of the capacity or throughput of institutions and service enterprises is carried out according to the calculated norms.
In accordance with the calculated data of public institutions, standard designs of public buildings are selected for a particular populated area. At the same time, it is advisable to give preference to such standard projects, which provide for the placement of several public institutions in one building. At the same time, the construction and operating cost per unit volume of the building is reduced, its appearance becomes more interesting, and the architecture of the public center where the building is located is enriched.
Concrete mortars are used for the construction of the foundation, the erection of walls and the pouring of the floor. Before the start of activities, it is important to choose the design of the foundation, correctly calculate the total level of costs and determine the required amount of building materials. Knowing how to calculate the volume of concrete, you can determine the estimated cost of construction activities, accurately plan the duration of the concrete work and avoid unexpected costs. Let us dwell in detail on the methodology for performing calculations for various, as well as walls and floors.
Strip foundation scheme
What methods can calculate the volume of concrete
The execution of construction work is preceded by the development of the project. At this stage, the type of foundation base is determined, and the volume of concrete solution required for the construction of the base is calculated. At the design stage, the need for a solution for pouring monolithic walls and a concrete floor is calculated. Determination of the cubic capacity of the concrete mix necessary for the performance of work is carried out according to the volume of the concreted structures of the building.
Various methods are used to perform calculations.:
- manual. It is based on the calculation of the volumes of the foundation, main walls and floor. The calculation is made on a conventional calculator according to school formulas for calculating volume and does not take into account the concrete shrinkage coefficient. The value obtained differs slightly from the results of calculations using software tools;
- program. The initial data entered into the program about the type of foundation, its dimensions, design features and brand of concrete are promptly processed. As a result, a fairly accurate result is produced, which you can focus on when purchasing building materials for building a foundation base, building walls or pouring a floor.
Features when calculating the volume of concrete To obtain an accurate result, it is not enough to take into account only the internal size of the formwork. The second method is more accurate, since the online calculator takes into account all the data: the type of foundation, the section of the foundation base, the presence of a reinforcing cage and the grade of mortar.
Getting ready to determine the volume of concrete - how to calculate without errors
When preparing to perform calculations, it should be remembered that the need for a concrete mixture is determined in cubic meters, and not in kilograms, tons or liters. As a result of manual or software calculations, the volume of the binder solution will be determined, and not its mass. One of the main mistakes that novice developers make is to perform calculations before the type of foundation is determined.
The decision on the design of the foundation is made after the following works have been completed:
- the production of geodetic measures to determine the properties of the soil, the level of freezing and the location of aquifers;
- calculation of the load capacity of the base. It is determined on the basis of weight, design features of the structure and natural factors.
How to calculate the amount (volume) of concrete mix - type of foundation being built;
- foundation dimensions, its configuration;
- brand of mixture used for concreting;
- soil freezing depth.
The accuracy with which the volume of concrete is calculated depends on the data used for the calculation.
They are different for each type of foundation.:
- when calculating the tape base, its dimensions and shape are taken into account;
- for a columnar base, it is important to know the number of concrete columns and their dimensions;
- you can calculate the cube of concrete for a solid slab by its thickness and dimensions.
The accuracy of the result obtained depends on the completeness of the data used for the calculation.
How to calculate concrete in cubes for a foundation
For all types of foundations, the need for concrete is determined by a formula that takes into account the total volume of foundation structures being erected. In this case, the part of the foundation poured into the ground is also taken into account without fail. To perform calculations, one should be guided by the dimensions indicated in the project documentation.
- columnar;
- grillage.
Determining the need for concrete mortar for each type of foundation has its own characteristics.
How to calculate a cube of concrete for a tape base
strip foundation calculator The base of the tape type is quite popular. It is used for the construction of private houses, outbuildings and country houses. The structure is a solid concrete strip reinforced with steel bars. Monolithic tape follows the contour of the building, including internal partitions.
Table of composition and proportions of concrete mix The calculation of the volume of concrete for a monolithic strip foundation is carried out using a simple formula V = AxBxP. Let's decrypt it:
- V - the need for a concrete solution, expressed in cubic meters;
- A is the thickness of the foundation tape;
- B - height of the tape base, including the underground part;
- P is the perimeter of the formed tape contour.
Multiplying these parameters together, we calculate the total cubic capacity of the concrete solution.
Consider the calculation algorithm for a strip base with dimensions of 6x8 m, a thickness of 0.5 m and a height of 1.2 m. Perform the calculation according to the following algorithm:
- Calculate the perimeter by doubling the length of the sides 2x(6+8)=28m.
- Calculate the cross-sectional area by multiplying the thickness and height of the tape 0.5x1.2 \u003d 0.6 m 2.
- Determine the volume by multiplying the perimeter by the cross-sectional area 28x0.6 \u003d 16.8 m 3.
The result obtained has a small error due to the fact that reinforced concrete reinforcement and mixture shrinkage during vibration compaction are not taken into account.
Strip foundation scheme How to calculate a cube of concrete for a pile type foundation
The base in the form of concrete columns is one of the simplest. It consists of reinforced concrete supports evenly spaced along the contour of the building, including at the corners of the building, as well as at the intersection of internal partitions with walls. Part of the support elements is located in the ground and transfers the load from the mass of the structure to the soil. The calculation algorithm provides for determining the total need for concrete by multiplying the volume of individual columns by their number.
For calculations, use the formula - V \u003d Sxn, which is deciphered as follows:
- V is the amount of solution for pouring columns;
- S is the cross-sectional area of the support element;
- n is the total number of pile columns.
Using the example of the requirements of a project involving the installation of 40 piles with a diameter of 0.3 m and a total length of 1.8 m, we calculate the required amount of concrete:
- Calculate the area of the pile by multiplying the coefficient 3.14 by the square of the radius - 3.14x0.15x0.15 \u003d 0.07065 m 2.
- Calculate the volume of one support by multiplying its area by the length - 0.07065x1.8 \u003d 0.127 m 3.
- Determine the required amount of the mixture by multiplying the volume of one pile by the total number of supports 0.127x40 \u003d 5.08 m 3.
How to calculate the cube of concrete With a rectangular section of the supporting columns, to calculate the cross section, it is necessary to multiply the width and thickness of the element.
How to calculate concrete for a column base with a reinforced concrete grillage
To improve the strength characteristics of the columnar base, the protruding parts of the supports are combined with a reinforced concrete structure, which is called a grillage. It is made in the form of a solid reinforced concrete tape or slab, in which the column heads are concreted.
How to calculate the volume of concrete for the construction of a strip foundation and piles - Determine the cross-sectional area of the grillage by multiplying its thickness by the height;
- Calculate the volume of the grillage by multiplying the cross-sectional area by the length of the structure.
The obtained value corresponds to the need for a concrete mixture for concreting the grillage base.
We calculate the volume of concrete for the foundation in the form of a solid slab
The slab type base is used on difficult soils with a high moisture concentration. Buildings without a basement are erected on it. This design allows you to evenly distribute the load from the mass of the structure on the soil and provide increased rigidity and stability of the object under construction. The use of reinforcement allows you to increase the strength of the slab foundation. The structure is a reinforced concrete slab in the shape of a rectangular parallelepiped.
How to calculate the volume of concrete Explanation of designations:
- V is the volume of concrete composition for pouring the slab;
- S is the area of the slab base in cross section;
- L is the length of the foundation structure.
For a foundation 12 m long, 10 m wide and 0.5 m thick, consider the calculation algorithm:
- Determine the area by multiplying the width of the slab by its thickness 10x0.5 \u003d 5 m 2.
- Calculate the volume of the base by multiplying the length of the structure by the area 12x5 \u003d 60 m 3.
The resulting value corresponds to the need for concrete mix. If the slab foundation has a complex configuration, then it should be divided on the plan into simpler figures, and then the area and volume should be calculated for each.
How to correctly calculate the cube of concrete for the construction of walls
Calculator for calculating the amount of concrete for a strip foundation on the site For the construction of massive buildings, strong boxes are constructed from concrete reinforced with steel reinforcement. To determine the need for building materials, builders face the task of calculating the volume of concrete for such structures. To perform calculations, use the following formula - V \u003d (S-S1) x H.
Let us decipher the notation included in the formula:
- V - the amount of concrete mix for building walls;
- S is the total area of the wall surface;
- S1 - total area of window and door openings;
- H is the height of the concreted wall box.
When performing calculations, the total area of the openings is determined by summing up the individual openings. The calculation algorithm is reminiscent of determining the need for concrete for a slab base and can easily be done independently using a calculator.
How to calculate a cube of concrete for pouring a floor
How to calculate the volume of concrete for the floor To increase the load capacity of the floor and ensure its flatness, a concrete screed is performed. After the concrete has hardened, such a surface serves as the basis for laying floor coverings or ceramic tiles. To prevent cracking, the thickness of the formed concrete screed is 5–10 cm. This is due to the fact that the thinner material cracks during operation. It is important to correctly calculate the cube of concrete so that the formed screed is strong and has the thickness provided for by the project.
The formula for determining the amount of solution V \u003d Sxh is easily deciphered:
- V is the amount of poured material;
- S is the total area of the concreted screed;
- h is the thickness of the concrete base.
Let's figure out how to perform calculations for a room with dimensions of 6x8 m and a concrete base thickness of 0.06 m:
- Determine the area of the floor surface by multiplying the length and width of the room - 6x8 \u003d 48 m 2.
- Calculate the volume of poured concrete composition to form a screed by multiplying the area by the layer thickness - 48x0.06 = 2.88 m 3.
Guided by the above algorithm, you can easily determine the amount of concrete composition for concreting the floor. There are situations when the rough surface has a slope. In this case, the formed screed has a different thickness over the area of \u200b\u200bthe room. In this situation, you can use the average layer thickness, which reduces the accuracy of the calculations.
Conclusion - why you need to know how to calculate a cube of concrete
Being engaged in construction and planning to independently produce a concrete solution or purchase it at the enterprises of reinforced concrete products in the required quantity, it is important to know how to calculate the volume of concrete. This will allow you to predict the amount of upcoming expenses, purchase building materials in a timely manner, and complete the work on schedule. You can make calculations both manually on a calculator and using software tools. The main thing is to master the calculation methodology and use reliable data to determine the amount of concrete.
Using the online calculator, you can correctly calculate the volume of a container such as: a cylinder, a barrel, a tank, or the volume of liquid in any other horizontal cylindrical container.
Determine the amount of liquid in an incomplete cylindrical tank
All parameters are indicated in millimeters
L- Barrel height.
H— Liquid level.
D- Tank diameter.
Our program will calculate the amount of liquid in the tank online, determine the surface area, free and total cubic capacity.
The determination of the main parameters of the cubature of tanks (for example, a conventional barrel or tank) should be made based on the geometric method for calculating the capacity of the cylinders. In contrast to the methods of calibrating the capacity, where the volume calculation is performed in the form of real measurements of the amount of liquid by means of a measuring ruler (according to the readings of the meter rod).
V=S*L is the formula for calculating the volume of a cylindrical tank, where:
L is the length of the body.
S is the cross-sectional area of the tank.
According to the results obtained, capacity calibration tables are created, which are also called calibration tables, and allow you to determine the weight of the liquid in the tank by specific gravity and volume. These parameters will depend on the filling level of the tank, which can be measured using a measuring rod.
Our online calculator provides the ability to calculate the capacity of horizontal and vertical tanks using a geometric formula. You can find out the useful capacity of the tank more accurately if you correctly determine all the main parameters that are listed above and are included in the calculation.
How to correctly define master data
Determine the lengthL
Using an ordinary tape measure, you can measure the length L of a cylindrical tank with a non-flat bottom. To do this, you need to measure the distance between the crossing lines of the bottom with the cylindrical body of the tank. In the case when a horizontal tank has a flat bottom, then in order to determine the size L, it is enough to measure the length of the tank along the outer side (from one edge of the tank to the other), and subtract the bottom thickness from the result.
Determine the diameter D
The easiest way is to determine the diameter D of a cylindrical barrel. To do this, it is enough to measure the distance between any two extreme points of the lid or edge using a tape measure.
If it is difficult to correctly calculate the diameter of the container, then in this case you can use the measurement of the circumference. To do this, using a regular tape measure, we wrap around the entire tank around the circumference. To correctly calculate the circumference, two measurements are made in each section of the tank. To do this, the surface to be measured must be clean. Having learned the average circumference of our container - Lokr, we proceed to determine the diameter using the following formula:
This method is the simplest, since the measurement of the tank diameter is often accompanied by a number of difficulties associated with the accumulation of various types of equipment on the surface.
Important! It is best to measure the diameter in three different sections of the container, and then calculate the average value. Since often, these data can differ significantly.
The averaged values after three measurements allow minimizing the error in calculating the volume of a cylindrical tank. As a rule, the used storage tanks undergo deformation during operation, may lose strength, decrease in size, which leads to a decrease in the amount of liquid inside.
Determine the levelH
To determine the liquid level, in our case it is H, we need a meter rod. With this measuring element, which is lowered to the bottom of the tank, we can accurately determine the parameter H. But these calculations will be correct for tanks with a flat bottom.
As a result of calculating the online calculator, we get:
- Free volume in liters;
- The amount of liquid in liters;
- Volume of liquid in liters;
- The total area of the tank in m²;
- Bottom area in m²;
- Side surface area in m².

Instruction
Find out the density (ρ) of the material that makes up the physical body whose volume you want to calculate. Density is one of two characteristics of an object involved in the formula for calculating volume. If we are talking about real objects, the average density is used in the calculations, since it is difficult to imagine an absolutely physical body in real conditions. It will definitely contain unevenly distributed at least microscopic voids or inclusions of foreign materials. Consider when determining this parameter and - the higher it is, the lower the density of the substance, since at the distance between it.
The second parameter that is needed to calculate the volume is the mass (m) of the body in question. This value is determined, as a rule, by the results of the object's interaction with other gravitational fields or the gravitational fields created by them. Most often, one has to deal with mass, expressed through interaction with the force of gravity of the Earth - the weight of the body. The methods for determining this value for relatively small objects are simple - they just need to be weighed.
To calculate the volume (V) of the body, divide the parameter determined in the second step - the mass - by the parameter obtained in the first step - the density: V=m/ρ.
In practical calculations, for calculations, you can use, for example, volume. It is convenient in that it does not require looking elsewhere for the density of the desired material and entering it into the calculator - there is a drop-down list in the form with a list of the materials most commonly used in calculations. After selecting the desired line in it, enter the weight in the "Mass" field, and in the "Calculation accuracy" field, specify the number of decimal places that should be present in the calculation result. The volume in and you will find in the table below. In the same place, just in case, the radius of the sphere and the side of the cube will be given, which should correspond to such a volume of the selected substance.
