# How to calculate liters in an aquarium by size

## How to calculate capacity in liters?

If bulk or liquid goods are packed into boxes, then to calculate the required volume, we use the ratio 1 m3 = 1000 l and, multiplying the resulting volume in m3 by 1000, we get the volume in liters. For our example, the volume of the box (internal) in liters is 0.0961000 = 96 liters.

## What you need to do to find the volume?

To calculate the volume of rectangular shapes (rectangular parallelepiped, cube), use the formula: volume = L × W × H (length times width times height). This formula can be considered as the product of the surface area of ​​one of the faces of the figure by the edge perpendicular to this face.

## How to calculate the amount of soil per site?

To estimate the volume, determine the area of ​​the area that you want to cover with nutrient soil, as well as the desired thickness of the fertile layer. Formula for calculation: multiply the area of ​​the site by the thickness of the coating. Example. Plantation 20 m2, layer thickness. 0.5 meters.

## How to calculate the volume of water in a pool?

cube). If the shape of your water tank is neither round nor oval, but has a free rounded shape, to find its volume, multiply the longest length by the widest width, then by the average depth and by a factor of 0.85. Large length (m) large width (m) average depth (m) 0.85.

## How to calculate how much soil you need for an aquarium?

So, the volume of soil required for laying in an aquarium is calculated using a simple formula: “length x width x height / 1000”. So, the product of the length, width and height of the soil layer is divided by 1,000, as a result, the volume of soil in liters is obtained.

## How to calculate the number of fish in an aquarium?

When calculating the number of aquarium fish, you can use the simplest formula:

• For a fish up to 5 cm long, you need 1-2 liters of water.
• For a fish longer than 6 cm, 6 liters will be required, at the rate of one liter per centimeter of fish length.

## How to calculate the displacement?

Volume is measured in cubic units, such as cubic centimeters (cm3). Convert cubic centimeters to liters. To do this, use the following ratio: 1 L = 1000 cm3. Divide the volume, measured in cubic centimeters, by 1000 to get the volume in liters (L).

### Data and tools

To calculate the useful volume, you will need measuring tools (ruler, tape measure, vernier caliper) and a calculator for calculations.

No additional tools are required. In the passport of the aquarium (if any), some values ​​are indicated. the thickness of the glasses, the total (geometric) volume and other indicators. They can be used for calculations, which will simplify the task and speed up the receipt of the result.

### Calculation rules

The calculation is done according to the following rules:

• Measure the length and width of the container, subtracting twice the thickness of the glass.
• Measure the height of the aquarium. The easiest way is to use a ruler and immediately measure the inner height so as not to subtract the thickness of the glass.
• Determine the final indicator according to the appropriate formulas.

Since it is precisely the internal volume of the reservoir itself that needs to be determined, the task is simplified and does not require additional actions.

### How to get the calculation correctly?

The volume is calculated according to the following rules:

• the inner size of the container is measured (outer size minus double glass thickness);

• a few centimeters (3-5) are subtracted from the full height, leaving some unfilled volume of the tank;
• subtract a few centimeters of the height of the soil;
• determine the volume of bottom structures, add filter sizes to them.

All additional volumes are subtracted from the calculated value, which results in the actual amount of water in the aquarium.

## Does the amount of water depend on the type of fish?

Different types of aquarium fish need their own living space.

For example, for small species (cardinal, guppy or neon), 1 liter is enough for each fish.

Larger views require much more space. For example, for a pair of cichlids up to 10 cm in size, about 40 liters will be required.

### What data and tools are needed?

• First of all, it is necessary to select the material for the tank. There are glass and acrylic containers, the wall thickness of which is noticeably different. Acrylic is thicker than glass.
• The second step is soil selection. The finer the fraction, the less you need to make corrections for loose packing of particles. If fine sand is used, it can be counted as continuous backfill. For large stones (pebbles or debris), the layer thickness when calculating is reduced by 10-15%, depending on the shape of the stones.

For measurements you will need:

• ruler or tape measure;
• vernier caliper for determining the thickness of the glass;
• calculator.

## How to calculate the usable volume based on the actual tank volume?

The calculation of the useful volume of the aquarium is based on the determination of the total amount of water that will fit in an empty tank.

To do this, you just need to determine the size of the tank without taking into account the thickness of the glass.

In this case, it is not required to make corrections for soil, incomplete filling of the container and for other additional elements.

## How to correctly calculate how many liters of water you need to fill in according to the size of the aquarium?

The volume of the aquarium is an important indicator that every tank owner needs to know. This is a value that gives an idea of ​​the quantitative and qualitative capabilities of the aquarium.

It allows you to calculate the amount of additives and determine the parameters of filtering installations, prepare the required amount of water for replacement and perform a lot of other calculations. So how do you calculate the volume?

## How to determine what the actual volume of water is?

The actual volume is the amount of water actually present in the tank. It differs from the usable volume, which is calculated based on the full dimensions of the container. However, water is never poured to the very edge.

• glass thickness;
• the volume of soil and bottom structures;
• number of plants, etc.

All add-ons take up some space and reduce the actual volume of water.

## How to calculate the number of fish in an aquarium

This article will show you how to calculate the number and size of fish to keep in your aquarium to keep them comfortable. These numbers should help you choose the right aquarium volume and avoid overcrowding in the future.

One of the biggest problems in aquarium hobby is the desire to purchase a large number of different types of fish in your aquarium. At the same time, creating uncomfortable conditions of detention, and thousands of times higher than the norm that is in the wild. All remaining difficulties in comparison with this moment fade into the background.

Amateurs aquarists constantly ask questions, which causes problems in the aquarium, with the further maintenance of fish. In keeping, very often, the problem is overpopulation of the aquarium, it turns out that in a 50-100 liter container, the “teapot” manages to populate that amount of fish, which corresponds only to a 400-500 liter aquarium. Please, do not follow in their footsteps, do not copy them, be guided by the permissible norms of the ratio of aquarium fish to the volume of a decorative aquarium.

### Calculation table for aquarium fish in an aquarium

 Types of aquariums Aquarium without filter, but with live plants Aquarium with starter equipment Aquarium with suitable equipment Small fish: zebrafish, neon, cardinal, rasbora, cherry barbus, etc. 1.5 liters per fish 1 liter per fish 0.5 liters per fish Medium fish: labyrinth fish, viviparous, barbs, small catfish, etc. 5 liters per fish 4 liters per fish 3 liters per fish Large fish: large haracinids and carps, medium catfish and cichlids, etc. 15 liters per fish 12 liters per fish 10 liters per fish Very large fish: catfish larger than average, large cichlids, knives, snakeheads, etc. It is not recommended to check in 60 liters per fish 40 liters per fish

When populating an aquarium with an initial set of equipment, well-established or poorly growing living plants, it is advisable to double the volume of water required for the safe keeping of fish.

When the aquarium is not equipped with filtering equipment, it is necessary to purchase a lighting fixture, a compressor and a water heater. In this case, with living plants, the bottom of the aquarium should be planted at least 50%.

An aquarium equipped with an initial set of equipment must additionally have an internal filter. The filter element must be flushed once a week or as needed.

An aquarium equipped with professional equipment, equipped with a powerful additional external filter, is serviced much less often. If the performance of the external filter decreases by about 50%, it is recommended to thoroughly rinse it. this is about once every two months.

Information on the density of fish population in aquariums is given only for the amount of water actually poured into the aquarium, that is, without taking into account the volume of soil, decorations, internal filters, etc.

We recommend that when starting an aquarium, provide for the population rates, taking into account the size of adult fish. I would like to remind you that the most important strategy for a novice aquarist is strict adherence to the above recommendations. This will keep your aquarium looking great at all times.!

## 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 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.

## Reservoir measurement by formulas

To measure the displacement of a container, simple tools are required. You need to prepare:

• A 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. height.

The resulting figures must 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: ABC0.001.

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 will be 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 H0.001.

The volume of a spherical reservoir can also be calculated using a ready-made formula. It is necessary to determine the radius of the ball (denoted as R), build the resulting value into 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: πR 3 0.001 ¾.

## How to calculate the displacement volume in an aquarium

For people who decide to engage in aquaristics, the question always arises of how to calculate the volume of the aquarium in liters and find the optimal size of the decorative reservoir. At first glance, this may seem insignificant, but in fact, the volume of the reservoir is very important for the normal functioning 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

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 is 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.

## Choosing the right size

The biggest mistake for a beginner is buying a pond that is too small. An aquarium is an ecosystem in which plants that produce oxygen develop, fish that eat algal bloom, shrimp 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, since the fish in them feel uncomfortable and are exposed to stress. 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.

Taking into account all the recommendations, you need to responsibly select the shape and size of the container, because a correctly selected reservoir will bring much less trouble to care for it.

## Calculator for calculating liquid in a barrel, tank, cylinder

### Instructions for the calculator for calculating the physical indicators of a round capacity

Using the online calculator, you can correctly calculate the volume of a container of the type: cylinder, barrel, 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.

Our online program will calculate the amount of liquid in the container, determine the surface area, free and total cubic capacity.

How to calculate the volume of a barrel

In order to correctly calculate the capacity of the tank to determine the amount of liquid and useful cubic capacity of a cylindrical tank, it is necessary to determine the main parameters of the tank. In our case, this is a horizontal tank.

The determination of the main parameters of the cubic capacity of tanks (for example, an ordinary barrel or tank) should be made based on the geometric method for calculating the capacity of cylinders. In contrast to the methods of tank calibration, where the volume is counted in the form of real measurements of the amount of liquid using a measuring ruler (according to the meter rod).

V = SL is the formula for calculating the volume of a cylindrical tank, where:

### How To Figure Out How Many Gallons Your Aquarium Is

S. cross-sectional area of ​​the tank.

According to the results obtained, container calibration tables, which are also called calibration tables, are created, which make it possible 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 meter rod.

Our online calculator provides the ability to calculate the capacity of horizontal and vertical containers using a geometric formula. You will be able to find out the useful capacity of the tank more accurately if at the same time you correctly determine all the main parameters that are indicated above and are involved in the calculation.

How to correctly identify the master data

Determine the length L

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 intersecting lines of the bottom with the cylindrical body of the tank. In the case when the horizontal tank has a flat bottom, then in order to determine the size L, it is enough to measure the length of the tank on the outside (from one edge of the tank to the other), and subtract the thickness of the bottom from the result.

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 an ordinary tape measure, we grasp the entire tank around the circumference. To correctly calculate the circumference, two measurements are made in each section of the tank. For this, the surface to be measured must be clean. Having learned the average circumference of our container. Lokr, we proceed to determining the diameter using the following formula:

This method is the simplest, since often measuring the diameter of the tank is accompanied by a number of difficulties associated with piling up on the surface of various types of equipment.

Important! It is more correct 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, used storage tanks undergo deformation during operation, they can lose strength, decrease in size, which leads to a decrease in the amount of liquid inside.

Determine the level H

To determine the level of the liquid, in our case it is H, we need a meter rod. With the help of 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;
• Liquid volume in liters;
• The total area of ​​the tank in m²;
• Bottom area in m²;
• Side surface area in m2.

## Calculator for calculating the volume of liquid in a rectangular container

### Instructions for an online calculator for calculating the volume in rectangular containers (such as an aquarium)

All values ​​are indicated in mm

This program calculates the volume of liquid in various sizes of rectangular containers, it will also help to calculate the surface area of ​​the tank, free and total volume.

As a result of the calculation, you will find out:

• The total area of ​​the tank;
• Lateral surface area;
• Bottom area;
• Free volume;
• The amount of liquid;
• Tank volume.

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 size, manually can be performed 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 tank. Next, you should carefully drain all the water into separate containers. For example, in 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 perform 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 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 receive a 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 = XYH) 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. 0.001×3000000 centimeters, and we get that the volume of our tank will be 300 liters. We calculated the full capacity of the tank, then it is necessary 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 (without taking into account the thickness of the glass).

Hence, the volume of our tank will be equal to 260 liters.
