How to calculate the volume of a box in liters. Calculation of the volume of liquid in a rectangular container
These calculations are required to determine the volume of the heating system, when choosing an expansion membrane tank.
Expansion volume membrane tank is selected on the basis of at least 10% of the total displacement of the system.
Determine the radius of the pipe R ... If it is necessary to calculate the internal volume of the pipe, then it is necessary to find the internal radius. If it is necessary to calculate the volume occupied by the pipe, the outer radius should be calculated. By measuring, the diameter (both internal and external) and the circumference of the pipe can be easily obtained. If the pipe diameter is known, divide it by two. So, R = D / 2, where D is the diameter. If you know the circumference of the pipe section, divide it by 2 * Pi, where Pi = 3.14159265. So, R = L / 6.28318530, where L is the circumference.
Find the cross-sectional area of the pipe. Square the radius value and multiply it by pi. So, S = Pi * R * R, where R is the radius of the pipe. The sectional area will be found in the same system of units in which the radius value was taken. For example, if the radius value is in centimeters, then the cross-sectional area will be calculated in square centimeters.
Calculate the volume of the pipe. Multiply the cross-sectional area of the pipe by its length. The volume of the pipe is V = S * L, where S is the cross-sectional area and L is the length of the pipe.

Technology for calculating the amount of liquid in tanks of various shapes
When a container is of an irregular geometric shape (for example, in the form of a pyramid, parallelepiped, rectangle, etc.), it is first of all necessary to measure the internal linear dimensions and only after that make calculations.
The calculation of the volume of liquid in a rectangular container of small dimensions can be done manually as follows. It is necessary to fill the entire reservoir with liquid to the brim. Then the volume of water in this case will be equal to the volume of the reservoir. Next, you should carefully drain all the water into separate containers. For example, into a special reservoir of the correct geometric shape or a measuring cylinder. On the measuring scale, you can visually determine the volume of your tank. To calculate the amount of liquid in a rectangular container, it is best for you to use our online program, which quickly and accurately performs all calculations.
If the tank is large and it is impossible to measure the amount of liquid manually, then the formula for the mass of a gas with a known molar mass can be used. For example, the mass of nitrogen is M = 0.028 kg / mol. These calculations are possible when the tank can be tightly closed (hermetically sealed). Now, using a thermometer, we measure the temperature inside the tank, and with a manometer, the internal pressure. Temperature should be expressed in Kelvin and pressure in Pascals. You can calculate the volume of internal gas using the following formula (V = (m ∙ R ∙ T) / (M ∙ P)). That is, the mass of the gas (m) is multiplied by its temperature (T) and the gas constant (R). Further, the result obtained should be divided into gas pressure (P) and molar mass (M). The volume will be expressed in m³.
How to calculate and find out the volume of an aquarium by size yourself
Aquariums are glass vessels that are filled with clean water to a certain level. Many aquarium owners have repeatedly wondered how large their tank is, how calculations can be performed. The easiest and most reliable method is to use a tape measure and measure all the necessary parameters, which should be driven into the appropriate cells of our calculator, and you will immediately get the finished result.
However, there is another way to determine the volume of the aquarium, which consists in a longer process, using a liter jar, gradually filling the entire container to the appropriate level.
The third method for calculating the volume of an aquarium is a special formula. We measure the depth of the tank, height and width in centimeters. For example, we got the following parameters: depth - 50 cm, height - 60 cm and width - 100 cm. According to these dimensions, the volume of the aquarium is calculated by the formula (V = X * Y * H) or 100x50x60 = 3,000,000 cm³. Next, we need to translate the result into liters. To do this, multiply the finished value by 0.001. Hence it follows - 0.001x3000000 centimeters, and we get that the volume of our tank will be 300 liters. We calculated the full capacity of the tank, then we need to calculate the real water level.
Each aquarium is filled significantly lower than its actual height, in order to avoid overflow of water, in order to close the lid taking into account the screed. For example, when our aquarium is 60 centimeters high, then the glued-in screeds will be located 3-5 centimeters lower. With our size of 60 centimeters, a little less than 10% of the volume of the container falls on 5-centimeter ties. From here we can calculate the real volume of 300 l - 10% = 270 l.
Important! A few percent should be subtracted taking into account the volume of glass, the size of the aquarium or any other container is removed from the outside (excluding the thickness of the glass).
Hence the volume of our tank will be 260 liters.

Length 60, height 100, width 60. find the volume of the tank in liters
There are several ways to calculate the volume in liters... If you come across a liquid that is packaged in a bottle, then there is always this volume indicated in liters... However, there are containers on which the volume is indicated in cubic meters. From elementary school it is known that 1 m ^ 3 = 1000 liters. Accordingly, if you need to find the volume of any container in liters, you have to multiply the given value in cubic meters by 1/1000: a (L) = b (m ^ 3) * 0.001. So you can calculate the volume in liters for a given volume, measured in m ^ 3. It is a simple conversion from one SI unit to another. However, if the volume is still unknown to you, you will first need to find it in meters, and then convert it to liters.
If you want to know approximately how much water fits into your existing aquarium, or if you are going to make a new one, then our volume calculator will help you quickly calculate aquarium volume rectangular or hexagonal.
Just choose which unit to use, centimeters or inches, and the shape of your aquarium. Results are reported in liters and gallons. The pictures above show how to take measurements.
The result is approximate, because the potential volume of the entire container is taken into account, i.e. the presence of soil, decorations, devices, etc. is not taken into account.

Sometimes it is very important to accurately calculate the volume of water passing through the pipe. For example, when you need to design a new heating system. Hence the question arises: how to calculate the volume of the pipe? This indicator helps to choose the right equipment for example, the size of the expansion tank. In addition, this indicator is very important when antifreeze is used. It is usually sold in several forms:
- Diluted;
- Undiluted.
The first type can withstand temperatures - 65 degrees. The second will freeze already at -30 degrees. To buy the right amount of antifreeze, you need to know the volume of the coolant. In other words, if the volume of liquid is 70 liters, then 35 liters of undiluted liquid can be purchased. It is enough to dilute them, observing the proportion of 50-50, and you will get the same 70 liters.
To get accurate data, you need to prepare:
- Calculator;
- Calipers;
- A ruler.
First, the radius is measured, indicated by the letter R. It can be:
- Internal;
- Outside.
The outer radius is needed to determine the size of the space that it will take.
For the calculation, you need to know the data of the pipe diameter. It is designated by the letter D and is calculated by the formula R x 2. The circumference is also determined. It is designated by the letter L.
To calculate the volume of a pipe, measured in cubic meters (m3), you must first calculate its area.
To get an accurate value, you first need to calculate the cross-sectional area.
To do this, apply the formula:
- S = R x Pi.
- The required area - S;
- Pipe radius - R;
- Pi number - 3.14159265.
The resulting value must be multiplied by the length of the pipeline.
How to find the volume of a pipe using the formula? You need to know only 2 values. The calculation formula itself is as follows:
- V = S x L
- Pipe volume - V;
- Sectional area - S;
- Length - L
For example, we have a metal pipe with a diameter of 0.5 meters and a length of two meters. To carry out the calculation, the size of the outer cross member of stainless metal is inserted into the formula for calculating the area of a circle. The pipe area will be equal to;
S = (D / 2) = 3.14 x (0.5 / 2) = 0.0625 sq. meters.
The final calculation formula will take the following form:
V = HS = 2 x 0.0625 = 0.125 cc meters.
This formula calculates the volume of absolutely any pipe. Moreover, it is absolutely not important what material it is from. If the pipeline has many components, using this formula, you can calculate separately the volume of each section.
When performing a calculation, it is very important that the dimensions are expressed in the same units of measurement. The easiest way to calculate is if all values are converted to square centimeters.
Using different units of measurement can lead to highly questionable results. They will be very far from their real values. When performing constant daily calculations, you can use the calculator's memory by setting a constant value. For example, pi times two. This will help to calculate the volume of pipes of different diameters much faster.
Today, for the calculation, you can use ready-made computer programs, in which standard parameters are indicated in advance. To perform the calculation, you only need to enter additional variable values.

How to calculate cross-sectional area
If the pipe is round, the cross-sectional area must be calculated using the formula for the area of a circle: S = π * R2. Where R is the radius (inner), π - 3.14. In total, you need to square the radius and multiply it by 3.14.
For example, the cross-sectional area of a pipe with a diameter of 90 mm. Find the radius - 90 mm / 2 = 45 mm. In centimeters, this is 4.5 cm. We square it: 4.5 * 4.5 = 2.025 cm2, we substitute in the formula S = 2 * 20.25 cm2 = 40.5 cm2.
The cross-sectional area of the profiled product is calculated using the formula for the area of a rectangle: S = a * b, where a and b are the lengths of the sides of the rectangle. If we consider the section of the profile 40 x 50 mm, we get S = 40 mm * 50 mm = 2000 mm2 or 20 cm2 or 0.002 m2.
Calculation of the volume of water in the entire system
To determine such a parameter, it is necessary to substitute the value of the inner radius into the formula. However, the problem immediately appears. And how to calculate the total volume of water in the pipe of the entire heating system, which includes:
- Radiators;
- Expansion tank;
- Heating boiler.
First, the volume of the radiator is calculated. To do this, his technical passport is opened and the volume values of one section are written out. This parameter is multiplied by the number of sections in a particular battery. For example, one is equal to 1.5 liters.
When a bimetal radiator is installed, this value is much lower. The amount of water in the boiler can be found in the passport of the device.
To determine the volume of the expansion tank, it is filled with a predetermined amount of liquid.
It is very easy to determine the volume of pipes. The available data for one meter, a certain diameter, just need to be multiplied by the length of the entire pipeline.
Note that in the global network and reference books, you can see special tables. They show approximate product data. The error of the given data is quite small, therefore, the values given in the table can be safely used to calculate the volume of water.
I must say that when calculating the values, you need to take into account some characteristic differences. Metal pipes with a large diameter pass the amount of water, significantly less than the same polypropylene pipes.
The reason lies in the smoothness of the pipe surface. In steel products, it is made with a large roughness. PPR pipes have no roughness on the inner walls. However, in this case, steel products have a larger volume of water than in other pipes of the same cross section. Therefore, in order to make sure that the calculation of the volume of water in the pipes is correct, you need to double-check all the data and support the result with an online calculator.

Conclusion
To find the exact figure for the consumption of the coolant of your system, you will have to sit a little. Either search the internet or use the calculator we recommend. Perhaps he can save you time.
If you have a water-type system, then you should not bother and carry out an accurate selection of volume. It is enough to estimate approximately. An accurate calculation is needed more in order not to buy too much and to minimize costs. Since many stop at the choice of an expensive coolant.
Enter the dimensions in millimeters:
D- the diameter of the container can be measured with a tape measure. It must be remembered that the diameter is the segment of the greatest length that connects two points on the circle and passes through its center.
H- The liquid level is measured using a meter rod, but if such a tool is not at hand, use a regular wire rod or wooden plank of suitable length. Observing safety measures, lower the rod strictly vertically into the tank to the bottom, mark the level on it, remove and measure with a tape measure. Also define H it is possible by measuring the distance from the top of the tank to the surface of the liquid and subtracting this indicator from the value of the diameter.
L- the length of the container.
If you need a drawing in paper form, it is advisable to mark the item "Black and white drawing". You will get a high-contrast image and be able to print it without wasting color ink or toner.
Tank volume- this parameter characterizes the total volume of the tank, i.e. what is the maximum amount of liquid in cubic meters or liters that can fit into it.
Amount of liquid- how much substance is in the tank at the moment.
Free volume allows you to estimate how much liquid can still be poured into the container.
As a result, you get a calculation of not only the volume of the tank, but also the volume of the liquid in the incomplete tank.
Metal products should be periodically painted, then their service life will increase significantly. Knowing anterior surface area, lateral surface area and total container area it is easy to estimate the required amount of paints and varnishes for processing the entire container or its individual parts.
For people who decide to engage in aquaristics, the question always arises of how to calculate the volume of an aquarium in liters and find the optimal size of a decorative reservoir. At first glance, this may seem insignificant, but in fact, the volume of the reservoir is very important for the normal life of fish. Some types of fish grow very quickly and require a large area. Therefore, the first priority for the aquarist is to select the correct capacity.
For the normal life of future pets, an aquarium of a certain volume is required. The need for calculation
Of course, if you need to calculate the aquarium in liters, you can always contact the seller in a specialized store for help. The numbers on the labels are approximate. The aquarium has an actual volume and a useful one, which is always less than the first, because no one fills it to the brim (because of the lamps on the lid). In addition, a layer of soil is always poured on the bottom, driftwood is laid and plants are populated.
A distinction should be made between the volume indicated in the documents and the useful volume of the aquarium. You can measure the capacity along the inner and outer walls. These measurements will vary as the glass tends to be quite thick. The size of the reservoir depends on the number of pets that can be settled in it. And also their number depends on stress resistance, aggressiveness and size of fish and other inhabitants.
Pet stores have a variety of pond care products: fertilizers, algae killers, water softeners, fish medications. All these additives are used strictly based on the volume of water in the aquarium. Therefore, it is very important to independently calculate the value to determine the exact dose of the drug and prevent overdose.
Reservoir measurement by formulas
To measure the displacement of a container, simple instruments are required. You need to prepare:
- Ruler... This role can also be played by a construction tape or centimeter.
- Calculator... With its help, it will be possible to carry out the final and accurate calculation.
In addition, you will need school knowledge of physics and geometry. The easiest way is to calculate the size of a cubic aquarium. Before calculating the volume in liters you need to write down its dimensions in centimeters:
- A - length;
- B - width;
- C is the height.
The resulting figures need to be multiplied, and the result will be the volume in cubic centimeters. To convert them to liters, multiply the resulting result by 0.001, that is, the calculation formula looks like this: A * B * C * 0.001.
To calculate the volume of the aquarium, you can use the ready-made formula Cylinder-shaped containers are very popular today. They are used as marine bodies of water. To calculate the volume of an aquarium by size, you need to measure the radius of the base in centimeters (denoted as R) and the height of the tank (H). The radius is squared, multiplied by Pi and the height. The result is the volume in cubic centimeters. Multiplying the value by 0.001 will give the container volume in liters. The formula looks like this: πR 2 * H * 0.001.
The volume of the spherical reservoir is also can be calculated using the ready-made formula... It is necessary to determine the radius of the ball (denoted as R), raise the resulting value to a cube, multiply by the number Pi and by ¾. Next, you need to remember to translate the resulting value into liters. The formula for such a capacity is πR 3 * 0.001 * ¾.
Other ways to determine the displacement
Sometimes it’s impossible to figure out how to calculate the volume using a formula. You can divide a complex figure into simple ones, fit it into a cube or circle, calculate the volume, cutting off extra liters. Fortunately, there is an easy way to determine the value. This will require any measuring container. It is easy to guess that the measured volume of water that has filled the aquarium is equal to its capacity.
In this way, you can more accurately find out how many liters are in the aquarium. This will take into account the volume of decorations, soil and devices in the water. The result will only give out the volume of water.
In order to find out the volume of the aquarium by size, you can use the services on the Internet. There are various online calculators on the net to determine the displacement of an aquarium of any shape. You just need to specify the required parameters.
Choosing the right size
The biggest mistake for a beginner is buying a body of water that is too small. An aquarium is an ecosystem in which plants that produce oxygen develop, fish that eat algal deposits, shrimps that feed on food leftovers. The larger the volume of the aquarium, the more complete the ecosystem in it.
The main thing in choosing an aquarium is that it does not turn out to be too small. For this reason, it is not recommended to buy a container of less than 50 liters for an apartment - caring for it will be quite problematic. The best option would be a 100-liter reservoir. It is better to refuse the round and intricate forms of the aquarium, as the fish in them feel uncomfortable and are stressed. In addition, it is difficult to plant plants in such a reservoir.
For fish, a low parallelepiped is preferable, with a base height of up to 70 cm. The height of a reservoir for fish is not a fundamental factor, but the plants will receive the necessary light.
