Convert cubic meters to cubic meters

As you know, a cubic meter is a unit of measure for volume. This fact is generally accepted. The side of such a cube is equal to 1 meter. This indicator is used to determine the volume of containers, for example, a tank, reservoir, or cistern.

One way or another, when calculating the volume, sometimes difficulties arise that are caused by the use of another unit of measurement of volume - liters. If you need to calculate the volume that is needed to store any substance, or to calculate the volume that a liquid occupies, then it will also be useful here to calculate their weight (mass), which, as a rule, does not correspond to the number of liters.

What is the difficulty in calculating the volume of the container?

For storage or transportation of such substances as methane, oil, gasoline, milk, water, a container with a certain displacement is required, which in practice is required to know in cubes, and sometimes in kilograms. Sometimes it becomes necessary to convert liters to tons.

The formula for calculating the volume for various substances is simple, but in practice errors are often encountered. Therefore, it will not be superfluous to take a few minutes and check yourself using our calculator. After all, an error in solving a problem can only be fraught with a bad estimate, but in practice, incorrect calculations can lead to the acquisition of capacity with insufficient volume, and this is an extra waste.

Instructions for using the online calculator

If you need to quickly convert liters to cubes, then our online calculator is for you. All that needs to be done is to select a substance from the list, the mass and volume for which you want to calculate and enter in the appropriate form the number of liters that you want to convert to cubes. By pressing the "Calculate" button, you will receive the desired values ​​of volume in cubic meters and mass.

Formula for calculating mass from volume

To calculate the volume of liquid, you can use the simplest formula from the school physics course

where V is the volume of the liquid (substance) in liters, m is the mass of the taken liquid (substance), p is the density of the liquid (substance).

When creating the calculator, we used the following density values ​​from the table below.

Density table of substances

If you have not found the required substance in the proposed list - write to us - we will definitely add it.

Before everyone who has decided to embark on the exciting and mysterious path of home aquaristics, sooner or later the question arises: how much aquarium to choose and how much aquarium do I have now? How to calculate this value, choose the optimal volume and why it is important, we will answer in the article.

Why is it better to calculate the volume yourself

Of course, you can also contact the consultants of the store where you are going to buy the container. As available, they are presented in standard sizes: 5, 10, 15, 20, 25, 70, 100 liters, etc. But there is a catch in these meager numbers. They are very exemplary. First, what volume we are talking about: after all, for an aquarium it is actual and useful, which is somewhat smaller (as a rule, the aquarium is not filled to the very edge, there are lamps on the lid, and about five centimeters of soil are placed on the bottom of the aquarium, snags are placed , stones, plants). Measurements can be carried out along the outer and inner walls, which can significantly affect the volume - the glass is capable of reaching a two-centimeter thickness.

What affects the volume of the aquarium

The volume of the aquarium depends on the number of fish (snails, shrimps, frogs, crayfish and other aquatic inhabitants) that you can start. Their number depends on the size, aggressiveness, territoriality and stress exposure of these animals. The modern world of pet shops offers a whole range of preparations for aquarium lovers: chlorinated water softeners, for the destruction of harmful algae, liquid mineral medicines for fish. As a rule, these additives should be applied based on the volume of water. Naturally, it is very important to know for sure the aquarium is just for you - overdose and poisoning of animals should not be allowed.

What you need to measure

It doesn't take much to measure the size of an aquarium. A ruler (a sewing centimeter is also suitable, a construction tape - any measuring device), a calculator and memory recovery of a school course in physics and geometry.

aquarium in liters. Formula for different types of aquarium

This will be easiest if the aquarium has the shape of a cube or parallelepiped. Before calculating the volume of the aquarium in liters by size, we write them down in centimeters. Let A be the length of the base, B the width of the base, and C the height of the aquarium. The result of multiplying these values ​​will give us the volume of the aquarium in cubic centimeters. To convert this value to liters, you need to multiply the resulting value by 0.001. That is, the formula looks like:

The volume of a cube-shaped aquarium in liters = A * B * C * 0.001.

The type of cylindrical aquarium is widespread (it is especially popular as a marine version). To measure its volume, we will measure in centimeters the radius of the base (denote R) and the height of the wall of the aquarium (denote H). Multiply the square of the radius by Pi and by the height. The result is the volume of the aquarium in cubic centimeters. How to calculate the volume of an aquarium in liters? Multiply by 0.001. The formula is converted:

The volume of a cylindrical aquarium in liters = πR ^ 2 * H * 0.001.

The volume of a spherical aquarium in liters = πR ^ 3 * 0.001 * 3/4.

How to calculate the volume of an aquarium in liters in other ways

Of course, using well-known formulas, you can divide this complex figure into several simple ones, inscribe it into a cube or a ball and, having calculated their volumes, mentally cut off the extra liters. But there is a much simpler and more reliable way. This requires a measured container and, in fact, the "jar" itself (our aquarium). It is logical that the volume of water that has filled the aquarium will be equal to its capacity. This method is good in that it can take into account the volume of soil, large decorative elements, plants, an internal filter and other devices already in the aquarium, and, accordingly, give out only the volume of water entering it. The Internet will come to the rescue. There are many online calculators on the network with which it will not be difficult to calculate the volume of an aquarium.

Choosing the size of your home aquarium

Now, knowing how to calculate the volume of the aquarium, you can proceed to this responsible choice. The main mistake that a beginner in this business can make is choosing too small a volume. An aquarium is a kind of ecosystem. There are plants that produce oxygen in the light during photosynthesis, there are fish that scrape off harmful algal plaque from the leaves and walls of the vessel, there are snails and shrimps that collect the remains of uneaten food and dead plant parts. The larger the aquarium, the more complete this ecosystem will be. Therefore, it is not recommended to start aquariums less than 50 liters - it will be difficult to care for them. The optimal aquarium size is from 100 liters.

And it is better to abandon or too intricate forms - the fish in them are more susceptible to stress, there are fewer opportunities to plant plants. Even banal aquariums with a rectangular base can serve different purposes: low aquariums are chosen for the paludarium (herbal aquarium). Shrimp can be of various shapes, but the most common - with a square bottom, "cubes".

And it is better to abandon aquariums that are round or too intricate - the fish in them are more susceptible to stress, there are fewer opportunities to plant plants. Even banal aquariums with a rectangular base can serve different purposes: low aquariums are chosen for the paludarium (herbal aquarium). Shrimp can be of various shapes, but the most common - with a square bottom, "cubes".

For aquarium fish, a slightly flattened parallelepiped with a height of no more than 70 cm will be good (for fish, height does not matter, but aquarium plants will not receive enough light and perform an aesthetic function). Thus, the volume, shape and size of the aquarium must be approached responsibly and wisely.

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 front 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.

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 of 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 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 area you are looking for - 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 the volume of each section separately.

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.

If you use different units of measurement, you can get very 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 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 bimetallic 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 the amount of liquid measured in advance.

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 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, 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.

Internal volume of a running meter of a pipe in liters - table

The table shows the internal volume of a running meter of the pipe in liters. That is, how much water, antifreeze or other liquid (coolant) is required to fill the pipeline. The inner diameter of pipes is taken from 4 to 1000 mm.

If you have a specific design or pipe, then the formula above shows how to calculate the exact data for the correct flow of water or other coolant.
