Convert liters to cubic meters

As you know, a cubic meter is a unit of 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 tank.

One way or another, when calculating volume, difficulties sometimes arise, which are caused by the use of another unit of measurement of volume - liters. If you need to calculate the volume needed to store any substance, or calculate the volume occupied by a liquid, then it will also be useful 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 a container?

To store or transport substances such as methane, oil, gasoline, milk, water, a container with a certain displacement is required, which in practice needs to be known in cubes, and sometimes in kilograms. Sometimes it becomes necessary to convert liters to tons.

The formula for calculating volume for various substances is simple, but in practice errors are often encountered. Therefore, it won’t hurt to take a few minutes and test yourself using our calculator. After all, a mistake in solving a problem can only lead to a bad estimate, but in practice, incorrect calculations can lead to the purchase of a container with insufficient volume, but this is an extra expense.

Instructions for using the online calculator

If you need to quickly convert liters to cubes, then our online calculator is for you. All you need to do is select from the list the substance whose mass and volume you want to calculate and enter the number of liters that you want to convert into cubes into the appropriate form. By clicking the "Calculate" button you will receive the required volume values ​​in cubic meters and mass.

Formula for calculating mass from volume

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

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

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

Substance density table

If you do not find the substance you need in the proposed list, write to us and we will definitely add it.

In order to calculate the volume of a body or substance in liters, you need to know its volume, expressed in other units of measurement. If the volume of a body is previously unknown, then it can be calculated through mass and density. There are special methods and tools for measuring mass and density.

You will need

• calculator, scales, substance density tables

Instructions

1. If the volume is given in cubic decimeters (dm?), then the volume is in liters expressed by the same number. Therefore, is it easy to change the unit of measurement dm? per liter (l).Vl=Vdm? To convert a volume given in cubic meters (m?) into liters, multiply the given numerical value by 1000.Vl=Vm?*1000To convert a volume given in cubic centimeters (cm?) into liters ) or milli liters(ml), divide the given numerical value by 1000.Vl=Vcm?/1000=Vml/1000.To calculate the volume in liters, if it is set in deka liters(dl) or buckets, multiply the number of deciliters by 10: Vl = Vdl * 10

2. If the volume is specified in non-metric units of measurement (national or household), use the following instructions: If the unit of measurement of the famous volume is the overseas gallon, then in order to calculate the volume in liters, multiply it by 3.7854. Do the same with other units of volume: overseas quart - multiply by 0.9464; overseas gallon - 3.7854; overseas dry barrel - 115.6270; overseas bushel - 35.2391; overseas liquid barrel - 119.2400; oil barrel - 158 .9873; imperial gallon - 4.5461; imperial quart - 1.1365; imperial pint - 0.5683; imperial ounce - 0.0284; overseas pint - 0.4732; overseas ounce - 0.0296; imperial bushel - 36, 3687; teaspoon - 0.005; tablespoon - 0.0148; mug - 1.23 (relatively); glass - 0.2; cubic inch - 0.0164; cubic foot - 28.3168.

3. If the volume of a body or liquid is unfamiliar, then calculate it using the following formula: V = m*p, where: V is the desired volume, m is the mass of the body, liquid or substance, p is its density. If the mass of the body is unfamiliar, then determine it weighing. Find the density of the substance in density tables. The resulting volume value will be in liters, if the mass is given in grams (g) and the density is given in grams per liter (g/l). In other cases, convert the volume into liters using the instructions above.

When working with small volumes, a unit of volume measurement such as milliliter (ml) is often used. A milliliter is a thousandth of a liter. That is, one liter contains one thousand milliliters. To convert liters to milliliters you don’t even need a calculator - just the simplest knowledge in mathematics.

You will need

• - pencil,
• - paper.

Instructions

1. In order to convert liters to milliliters, simply multiply the number of liters by 1000. That is, apply the following primitive formula: Kml = Kl x 1000, where Kml is the number of milliliters, Kl is the number of liters. So, say, one teaspoon contains approximately 0.005 liters of liquid. Consequently, the volume of a teaspoon, expressed in milliliters, will be: 0.005 x 1000 = 5 (ml).

2. If the number of liters is an integer, then to convert liters to milliliters, simply add three zeros to the number of liters on the right. Let's say that one bucket holds approximately 10 liters of water. This means that the volume of this water in milliliters will be: 10 x 1000 = 10,000 (ml).

3. If the number of liters is given as a decimal fraction, then move the decimal point three places to the right. Let's say a kilogram of gasoline occupies a volume of approximately 1.316 liters. Consequently, in milliliters a kilogram of gasoline will have a volume of 1316 (ml).

4. If there are less than 3 digits after the comma, then fill in the missing digits with zeros. So, say, one glass holds 0.2 liters of liquid. In milliliters it will be 200 (ml) (officially it turns out to be 0200 ml, but the insignificant zero on the left can be discarded).

5. If all the initial data of the task are given in liters, and the result needs to be presented in milliliters, then carry out all intermediate calculations in liters, and convert to milliliters only after all calculations are completed. For example, if 1.325 liters of black paint were mixed to prepare paint of the required shade, 0.237 liters of red, 0.587 liters of green and 0.54 liters of blue, then to calculate the total amount of paint in milliliters, add the indicated numbers in liters, and multiply the total by 1000.1.325 + 0.237 + 0.587 + 0.54 = 2.6892.689 x 1000 = 2689 (ml).

Note!
Converting liters to milliliters is often used in calculations related to the preparation of medications and other energetic solutions. When making such calculations, be very careful - if each error is one decimal place, the result will change tenfold.

Helpful advice
Please note that the density of water is 1000 g/l or 1 kg/l or 0.001 t/l. Consequently, in order to calculate the known mass of water in liters, it is easy: divide the mass in grams by 1000; multiply the mass in tons by 1000; take the mass of water in kilograms equal to the volume in liters.

An aquarium is a glass vessel filled with water in which fish and plants live. When looking at an aquarium, a question spontaneously arises for the owner of an apartment or office - how many liters are in this aquarium?

The same question arises when you read the instructions for preventive and curative medications. Therefore, a very interesting and ambiguous 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 a 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 aquarium being measured, 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, 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 less to avoid water overflows and to take into account the aquarium ties that are closed with a lid. With an aquarium height of 60 cm, as a rule, the ties are glued 3-5 cm lower and the height of the filling part is the same. 5 cm to the 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 real volume.

– 300 liters – 10% = approximately 270 liters;

We subtract another couple of percent for the volume of the glass, since we measured the aquarium from the outside without taking into account the thickness of the glass.

Total: There are approximately 260 liters of water in the aquarium.

In fact, after placing soil, decorations and fish in the aquarium, they will displace a little more water with their weight, but this is 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 matters related to aquarium maintenance in Kyiv, or on other issues, please contact us. You will find contact information for contacting us. Waiting for you!

For everyone who has decided to take the exciting and mysterious path of home aquarium keeping, sooner or later the question arises: what size aquarium should I choose and what size aquarium do I currently have? How to calculate this value, choose the optimal volume and why this 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. Firstly, what volume are we 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, lamps are located on the lid, and about five centimeters of soil are placed on the bottom of the aquarium, driftwood is placed , stones, plants). Measurements can be taken on the outer and inner walls, which can significantly affect the volume - glass can reach a thickness of two centimeters.

What does the volume of the aquarium affect?

The volume of the aquarium determines the number of fish (snails, shrimp, frogs, crayfish and other aquatic inhabitants) that can be kept. Their number depends on the size, aggressiveness, territoriality and stress of these animals. The modern world of pet stores offers a whole range of products for aquarium lovers: products to soften chlorinated water, to kill 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 exactly which aquarium is right for you - overdose and poisoning of animals must not be allowed.

What you need to measure

To measure the size of an aquarium, you don't need much. A ruler (a sewing centimeter, a construction tape - any measuring device is also suitable), a calculator and a 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 is in the shape of a cube or parallelepiped. Before calculating the volume of the aquarium in liters by size, let's 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:

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

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

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

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

Choosing the size of a home aquarium

Now, knowing how to calculate the volume of an aquarium, you can begin 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 through the process of photosynthesis, there are fish that scrape harmful algae from the leaves and walls of the vessel, there are snails and shrimp that collect the remains of uneaten food and dead parts of plants. The larger the aquarium, the more complete this ecosystem will be. Therefore, it is not recommended to have aquariums smaller than 50 liters - they will be difficult to care for. The optimal size of the aquarium is from 100 liters.

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

And it is better to abandon aquariums that are round or too intricate in shape - the fish in them are more susceptible to stress, and there are fewer opportunities to plant plants. Even banal aquariums with a rectangular base can serve different purposes: low aquariums are chosen for a paludarium (herbal aquarium). Shrimp tanks can come in a variety of shapes, but the most common are those 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, the 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 with all responsibility and intelligence.
