How the volume is calculated in liters. Calculation of the volume of liquid in a rectangular container
For a specific cargo, you must first calculate its volume. This value reflects the maximum capacity of the corrugated container.
Calculation of the volume of boxes
The cardboard boxes are square or rectangular. In this case, they represent a parallelepiped. We know from the school course that to calculate the volume of this figure length, width and height are required... Dimensions can be measured using a regular ruler or tape measure.
The calculation of the volume, based on the size of the box, can be done using the formula:
Calculation formula:
V = a * b * h.
Where a - base length (mm),
b - base width (mm),
h - box height (mm),
V - volume (l).
This formula is the calculation of the volume of a parallelepiped. Therefore, it can only be used for rectangular boxes.
For those cases when the container has a non-standard shape, you can calculate its volume using the formula:
Calculation formula:
V = S * h.
Where S is the area of the base, which is calculated depending on its shape. In the case of triangular, hexagonal or octagonal bases, the area is calculated using different formulas.
Since the unit of volume in the international system of measurements (SI) is cubic meters (m 3), it is more correct to translate the size of length, width and height into meters. For those who are used to working with centimeters or millimeters, you can leave this dimension. But when calculating the volume of cargo, you will have to use only it.
Internal and external volume of the box
Knowing the exact volume of the corrugated box, you can easily select a suitable load. To do this, use the same technique to calculate its volume. If the load has a complex configuration, then the overall dimensions must be used for calculations. It is clear that the volume of the container should be slightly larger.
When choosing a load, it is also necessary to take into account whether the volume of the boxes was calculated based on the internal or external dimensions. The results will vary slightly. In some cases, this can make a difference.
For this reason, it is advisable to use the inner dimensions of the container to accurately determine the permissible dimensions of the cargo. The dimensions of boxes and loads should differ from each other by 5-10 mm. The outer dimensions of the boxes are necessary when filling the body of vehicles for their transportation. They may also be required when calculating the required storage area.
Step-by-step instructions for calculating volume
We got acquainted with the necessary theoretical information for calculating the volume of the box. Let's look at the steps described above step by step.
We measure the length of the box. It means the size of the longest side of the base. We use a tape measure or a ruler for this. We translate the resulting size into meters and write it down. For small containers, measurements are easier to take in centimeters or millimeters. If you decide to use one of these dimensions, please note that the other dimensions, including the dimensions of the cargo, must be measured in the same dimension.
We measure the width of the box. This is the size of the shorter side of the base. We apply the same units of measurement. We write down or remember the result obtained. For fully square boxes, the length and width are the same.
At the next stage, in accordance with the formula for calculating the volume, we multiply all the dimensions obtained. If in the process of measurements we found that the size of our box is 100x200x300 mm, then the volume in this case is the product of all three quantities. V = 100х200х300 = 6 000 000 mm 3 or 0.006 m 3.
In some cases, there is a need to convert the resulting value to liters (l). Knowing the number of cubic units makes it possible to understand how many such cubes can fit inside a particular box. When packing liquid, small or bulk goods that occupy the full volume of the container, this value must be expressed in liters. For this we use the ratio 1 m 3 = 1000 l. In our case, V = 0.006x1000 = 6 liters.
We remind you that this technique can only be used for rectangular or square cardboard products. For other cases, you will have to recall the school geometry course more deeply. Use a formula to find the area of a polygon. From it you can calculate the base area of your container. By multiplying it by the height, you can easily get the amount of volume.

Calculation of the volume of cargo in m3
You can calculate the volume of cargo in m3 in our calculator. Why and who needs it? For example, you are a shipper who wants to understand the prices of the freight market and, for a start, wants to quickly calculate the volume of your cargo in m3. You can use a calculator to calculate. By specifying the dimensions of the sides and the height of one box, then specifying the number of boxes, as a result, we get their volume. Moreover, in this calculator you can see both the volume of the entire cargo, and only one box. Having found out the volume of your cargo, you can easily understand what kind of transport you need. Indeed, if the volume of your cargo is 10m3, then there is no need to order a truck and overpay for "emptiness". A gazelle will be enough for you.
How to calculate the volume of a box in cubic meters
It is very easy to calculate the volume of the box. There is a calculator on this page that will help you easily calculate the volume of one box or the entire load. Perhaps you are wondering what formula is used for the calculation. From the point of view of mathematics, an ordinary cardboard box with a load is a rectangular parallelepiped, and if all sides of the box are equal, then it is a cube. Accordingly, their volume will be calculated using a simple geometric formula: side A * side B * height. It is worth noting an important fact: if a value is used in the calculations, for example, a meter, then the result will be in cubic meters. Our calculator uses meters to calculate volume. If one of the sides of the box is, for example, 60cm, then in the calculator you need to specify a decimal fraction in the form: 0.6.
Calculator of the volume of a box with a load in m3
We have already figured out how the volume in m3 is calculated. In order not to calculate this value manually, this volume calculator was created. Why use this calculator? It is convenient, you do not need to waste time calculating the volume of the entire cargo in cubic meters (m3). Using the simple interface of our calculator, you can instantly find out the volume of the cargo. Just enter the dimensions of the sides of the box, the height of the box (third side) and the number of boxes, if there are more than one. And that's all, we get the result as a value in the format m3 (cubic meters).
Why is it better to use our calculator instead of manual calculations? The probability of an error in this case is excluded, and you also need to spend much less time and effort on manual calculations.
Why know the volume of the transported cargo?
If you are going to order the transportation of something packed in boxes or rectangular containers, then the first thing you will be asked when placing an order is the volume of the transported cargo. This is where our volume calculator in m3 will help you. Right during the call, you can quickly calculate the volume in m3 and report it for registration of the application.
Knowing the volume, the logistics manager will be able to select the necessary vehicle for the transportation of your particular cargo and will save you from unnecessary overpayments for a larger vehicle. Also, the logistician will immediately be able to guide you on the price of transportation.
An aquarium is a glass vessel filled with water in which fish and plants live. When you look at the aquarium, a question arises without permission to the owner of an apartment or office - how many liters are there in this aquarium?
The same question arises when you read the instructions for preventive and curative drugs. Therefore, a very interesting and controversial question - "How to calculate the volume of an aquarium?".
Of course, you can calculate it by pouring water out of it with a liter jar, but it is much easier to do this using the formula, and measuring with jars can be left for small round aquariums.
Step-by-step instructions for calculating the displacement of your aquarium:
First, we measure the dimensions of the measured aquarium, for example: the width of the aquarium is 100 cm, the depth from the front to the back wall is 50 cm, and the height of the aquarium is 60 cm.That is, it turns out:
- 100 cm * 50 cm * 60 cm = 300,000 cubic centimeters;
Now, to get the number of liters, we multiply this value by 0.001:
- 300,000 cc * 0.001 = 300 liters;
As a rule, the height of the filling part of the aquarium is lower in order to avoid overflow of water and take into account the aquarium screeds, which are closed with a lid. With an aquarium height of 60 cm, as a rule, the screeds are glued 3-5 cm lower and the height of the filling part is the same. 5 cm to screeds at a height of 60 cm is less than 10 percent: Total: it turns out that the estimated volume of the measured aquarium is 300 liters. But this volume is literally calculated - and we need a real volume.
- 300 liters - 10% = 270 liters approximately;
We subtract a couple more percent on the volume of the glasses, since we measured the aquarium from the outside without taking into account the thickness of the glasses.
Total: water in the aquarium comes out about 260 liters.
In fact, after placing the soil, decorations and fish in the aquarium, they will displace some more water with their weight, but this is already little taken into account, since without decoration and fish, the aquarium will not be an aquarium.
And yet, in my opinion, the volume of the aquarium is not so significant if it gives you real pleasure. If you need our help in any questions regarding the maintenance of the aquarium in Kiev, or for other questions, please contact us. You will find contact information for communication with us.

Often people buy aquarium fish without thinking about what kind of tank they need. With such a purchase, it is very important to calculate the volume of the aquarium in liters. Much depends on this characteristic: how many pets will live there, the volume of water, the amount of soil, etc. In fact, every adult knows how to calculate the volume of an aquarium; you just need to remember the knowledge gained at school.
What are the calculations for?
It would seem that there is nothing easier - to buy a fish house, all the necessary components and place underwater inhabitants there. In fact, if the owner of the fish did not calculate the volume of the tank correctly, her pets may not live in it for long.
- to understand how many fish and plants will be optimal for a particular pet house;
- determine the amount of soil and fertilizers;
- even when calculating the dosage of medicines for pets, you need to know the data of the aquarium.
The fish house should be comfortable for its inhabitants, then there will be no problems with the health of the pets.
How is the calculation made?
To understand how to find out the volume of an aquarium, you need to resort to the queen of all sciences - mathematics. Calculations will help determine how many liters will be required to fill it, which heater and water filter to choose, which species of fish can exist in it. Correct calculations are the key to the longevity of underwater inhabitants.
To calculate the volume of the aquarium, it is worth preparing special measuring instruments. The volume of the aquarium can be calculated using a calculator, tape measure and a pencil with a piece of paper. When you have prepared everything necessary, you need to follow the instructions and remember what you went through at school:
- calculate the volume of the aquarium, which has the shape of a parallelogram (this is a standard type of product), it is necessary to measure its length outside, depth and width;
- these three values in the aquarium should be written down on a piece of paper, they will be useful for further calculations;
- the displacement of the tank using the measured numbers is calculated by the formula: internal length × internal width × internal height;
- the question remains how to calculate the internal values, for this you need to measure the tank wall, its thickness;
- the resulting figure must be multiplied by 2, then subtract it from the previously obtained external measurements, which will help to obtain the internal numbers;
- then we substitute the values into the formula described above, and converts the resulting value into cubic liters (1 m 3 = 1000 l) - this will be the volume of the aquarium or displacement.
There is an additional specific way to measure the displacement of the tank. It is a little simpler than the previous one. It is necessary to make calculations according to the formula: (H × D × D) × 0, 001 (where H is the height in cm, D is the length in cm, D is the depth in cm). Thus, it turns out to correctly subtract liters.
Sooner or later, everyone who has decided to embark on the exciting and mysterious path of home aquaristics is faced with the question: 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 two centimeters in 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 building tape measure - any measuring device), a calculator and restoration in the memory 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.
