If we know the mass of the object, and you want to determine its volume, then turn a specified number of kilograms to cubic meters. To do this, divide the mass of the object to its density. That is, use the formula:

Km3 / Yr = Kkg / P,

where Km3 - the number of cubic metres,

Kkg – the number of kilograms

P – density of the substance expressed in kg/m3.

Km3 / Yr = Kkg / P,

where Km3 - the number of cubic metres,

Kkg – the number of kilograms

P – density of the substance expressed in kg/m3.

Example.

What tank capacity will need to store tons (1000 kg) of gasoline?

Solution.

1000/750=1,33333 m3.

Rounding in this and similar cases it is better to produce in a big way, as the density of matter is not constant and depends on many factors (temperature, humidity, etc.).

Therefore, the "correct" answer will be: 1.4 cubic meter.

If the density is unknown, determine it according to the appropriate tables of the density of a substance. Note that the density of the substance must be indicated in kilograms per cubic meter (kg/m3). This unit is the density of a substance is standard and found in most dictionaries. However, in practice you can often find other, non-si unit of measurement of density of liquid and solids – grams per litre (g/l). The numerical value of density specified in g/l, can be used as kg/m3 without any coefficients. If the density of a substance is specified in kilograms per liter (kg/l), to translate it in kg/m3 divide this value by 1000.

Clearly these rules can be written in the form of simple formulae:

Pkg/m3 = Ng/l

Pkg/m3 = Pkg/l / 1000,

where: Pkg/m3 PG/l, Pkg/l – density given in kg/m3, g/l, kg/l, respectively.

Clearly these rules can be written in the form of simple formulae:

Pkg/m3 = Ng/l

Pkg/m3 = Pkg/l / 1000,

where: Pkg/m3 PG/l, Pkg/l – density given in kg/m3, g/l, kg/l, respectively.

If the substance for which you want to translate kilograms into cubic meters - water, simply divide the number of kilograms by 1000. Use the same rule for determining the volume of low-concentrated solutions of substances. Of course, it must be a real solution, and not the same consistency as, for example, "the cement solution".

5

If the object consists of an unknown substance or mixture of substances, try to determine its density alone. To do this, separate the part of the object, determine its mass and volume, and then divide the mass by the volume. If the substance is a liquid, pour the liquid into a measuring capacitance, determine its mass (net) and divide by the volume. Similarly, we can determine the density of bulk materials.

# Advice 2: How to convert to cubic meters

A unit of volume in standard SI units - cubic

**meters**, but we do not always meet the task. In this regard, there is a need to translate the value from a specified unit in cubic**meters**. How to do it?Instruction

Cubic meter - the volume of a cube with an edge length of one meter. Remember that translate to in cubic

**meters**only the volume, but not mass, length or area.2

The translation of the volume units associated with meters, but with any set-top boxes (decimeter, centimeter, millimeter, micrometer, nanometer, kilometer), the standard translation mechanism.To translate cubic kilometers to cubic

**meters**comnote the number 10 to 9 degrees.To translate cubic decimeters to cubic**meters**, divide the number by 10 to 3 degrees.To translate cubic inches, divide by 10 to the 6th degree.To translate cubic mm divide by 10 to 9 degrees.To translate cubic micrometers, divide by 10 to 18 degrees.To translate cubic nanometers, divide by 10 to 27 degrees.3

Now consider a liter. 1 liter is the same as 1 cubic decimeter. Accordingly, to convert from liters to cubic

**meters**, divide the number by 10 to 3 degrees.1 milliliter is equal to 1 cubic meter. So, to convert from milliliters to cubic**meters**, you need do nothing.4

If the problem is from the mass to volume (e.g. pounds

**meters**cubic), you need to know the density of the substance. Use the physical formula m=p*V (m is mass, p is the density, V is the volume).# Advice 3: How to convert kg to cubic meters

At the decision of physical tasks is often required to translate physical quantities from one system of measure to another. As a rule, this process does not cause special difficulties. Units of homogeneous physical quantities are linked through their respective coefficients (occasionally, simple formulas). However, in practice, sometimes you have to work with heterogeneous values and translate, for example, kilograms per cubic meter

Instruction

1

To convert a known amount of kg per cubic meter, find the density of a substance to which he is transferred. To do this, locate the appropriate table of the density of a substance. For convenience of calculations the density of the substances in this table should be indicated in kilograms per cubic meter (kg/m3). This is the standard unit of density in the SI (system international).

2

Defining the table the matter density, use the following formula:

KMK = Kkg / P,

where: KMK – the number of cubic meters,

Kkg – number kg (kilograms),

P – density of the substance expressed in kg/m3.

For example, suppose you want to calculate what volume (how many cubic meters is 10 tons (10,000 kg) of decking.

Solution:

Find (online) the density of the decking. It is 800 kg/m3. Using the above formula, we can calculate that the number of cubic meters will be:

10000 / 800 = 12,5

KMK = Kkg / P,

where: KMK – the number of cubic meters,

Kkg – number kg (kilograms),

P – density of the substance expressed in kg/m3.

For example, suppose you want to calculate what volume (how many cubic meters is 10 tons (10,000 kg) of decking.

Solution:

Find (online) the density of the decking. It is 800 kg/m3. Using the above formula, we can calculate that the number of cubic meters will be:

10000 / 800 = 12,5

It often happens that to determine the density of the substance in the tables difficult. For example, some tables may not be at hand or don't know the name of the substance. Sometimes items can be constructed from several materials, combined in unknown proportions. Moreover, even the known density of the substance (material) can vary within wide limits (for example, the density of wood depends on its moisture content).

4

If you define the density of matter in the following table, measure it yourself. For this (possible) separate a piece of material, preferably of regular shape and calculate its volume in cubic meters. For example, if boards, then sawed off smoothly about half-meter segment of the Board. Then measure (in meters) the length, width and thickness of the sample. Multiply these numbers – the resulting work would amount. Now weigh the scrap Board and divide his weight (in kg) to the previously calculated volume (m3). The resulting number will be equal to the density of the Board in kg/m3.

5

If the cubic meters it is necessary to translate a known amount of a kilogram of water or weak solutions of other substances, the liquid density can be taken equal to 1000 kg/m3. This density value can be used in the rough (estimated) calculations of the volumes of other liquids.

To get an accurate value of the density of the liquid, pour the liquid in a measuring cylinder or fill her a container of known volume. Then weigh the liquid container and divide its mass (excluding the weight of packaging) per volume. Follow the same procedure to obtain the density of bulk materials.

# Advice 4: How to convert cubic meter to liter

The volume parameter of solid, liquid and gaseous bodies that defines the set of dimensional characteristics of the body. Mathematically it is a product of length, width and height of the body. That is why in the international system of units it is measured in cubic meters. But often in life there are other units of volume such as liter, milliliter, cubic centimeter.

According to the physico-mathematical theory of one liter equals zero point one thousandth of cubic meters, that is 1 liter = 0.001 m^3 (where m^3 – means "cubic meter"). Then one cubic meter is equal to one thousand liters, 1 m^3 = 1000L.

Based on the above rules, it follows the algorithm: to convert cubic meters to liters, multiply the given in the problem statement numerical value by one thousand. For this purpose the comma from numbers on move three characters to the right.

Example 1. May need to translate 5 cubic meters to liters. Solution: 5 m^3 = 5*1000 = 5000 liters.

Example 2. May need to transfer of 0.5 cubic meters to liters. Solution: 0.5 m^3 = 0,5*1000 = 500 L.

Example 3. May need to translate 57 cubic meters to liters. Solution: 57 m^3 = 57*1000 = 57000 L.

Imagine yourself the owner of a wonderful aquarium. In one cubic meter of water can accommodate a myriad of marine life and arrange a real underwater Kingdom with strange algae and fanciful compositions of rocks. But such beauty requires constant care. Once a week when cleaning the aquarium you need to drain some water and refill with fresh water. Sea water will not pour from the tap, you need to prepare the necessary amount in advance. You will have to determine how many liters is the updated portion of water. All chemicals to maintain the desired composition of the water and the health of the inhabitants of the aquarium added to the water in amounts exactly corresponding to the volume. Usually the user is given the rate of reagent per liter of water.So you'll have to determine how many liters in a cubic meter.

Cubic meter is easy to imagine as a cube with a rib size of one meter.The volume of such a cube (V) is equal to the product of the three dimensions that a cube is the same: V=1m х1м х1м=1 cub.kubicheskii meter large enough volume for everyday use much smaller capacity.Divide each edge of the cube into sections one centimeter. The prefix "centi" means "hundredth part", i.e., the centimeter is one hundredth of a metre. So, each edge of the cube is divided into one hundred segments. Connect the ends of the lines on opposite edges, and each face of the cube will be divided into squares with sides of one centimeter.Count the number of squares (n) on each face of the cube: n =100 x 100 = 10 000

# Advice 6: How to translate kilograms to liters

Kg - measure of mass of a substance used in the international system of units SI, and a liter is a volume measure, not included in this system. The physical characteristics of the bodies, measured in these units, are linked by a ratio that involves another parameter, the density of the substance. With the knowledge of two of the three options - for example, weight and density - to calculate the third volume is not working.

Instruction

1

Start from the General formula connecting the mass (m), density (p) and volume (V): V=m/p. For example, the initial conditions given the mass of liquid helium that is equal to 100 kg, and is proposed to calculate its volume at standard atmospheric pressure. The density of this substance is 130 kg/m3, so 100kg would correspond to a volume approximately equal to 100/130≈0,7692307692307692м3.

2

Put the units of the metric system, in which the obtained result of the calculation in

**liters**. In the SI system to measure volume, use cubic meters, and holds one liter is one cubic decimeter, and therefore increase the resulting value a thousand times - so many cubic decimeters are each cubic meter. In your example the answer should be a value equal to 769,2307692307692 L.3

When solving practical problems, consider the change in the density of a substance when heated. In various reference tables, the density of a liquid is given together with the indication of the measurement conditions, including temperature. And in various regulatory documents specify correction factors separately for summer and winter periods. For example, for diesel fuel summer correction factor equal to 1.03, and winter - 1,045.

4

If you define kilograms of the required liter volume solids, and still consider the heterogeneity of the material. For example, in stolitrovyh a barrel of sand contains not only the substance, but certain quantity of air between the individual grains. This number depends on the particle sizes (particle size) components of the bulk material. In addition, the easily deformable substances can be compacted, thereby increasing the average density. So, for example, the weight of cement of mark M500 in stolitrovyh barrel may not correspond to the calculations made based on the tabular density of the substance.

# Advice 7: How many kilograms in one liter

The answer to the question "How many kilograms in one liter?" is very ambiguous and depends on many parameters that are worth to perform. For example, it is the nature of the substance, temperature, number of voids, etc.

The value that shows the number of kilograms in a liter of a substance is called density.

Is the average density of body, density of the substance, the density of the body at the point. The average density of a body is the ratio of body mass to its volume. The density of a substance is the ratio of the mass of a substance to its volume. The density of the body at the point is the ratio of body mass to volume, which tends to zero.

Another is the true and apparent density. True density is the density that is defined without consideration of voids, and the apparent taking into account the voids.

It is established that the density of the material with increasing temperature decreases. This is due to increasing porosity. However, in nature, occurs in a number of substances, the density of which deviates from the General relation. So, water has a maximum density of 1 kg/l, it is achieved at a temperature of + 4oC. As temperature decreases, its density decreases, reaching 0.93 kg/l (below 0 oC). That's why ice floats on water.

When switching from one aggregate state to another the density changes abruptly.

2. Density of river water is 1 kg/L.

3. The density of granite is 2.6 kg/l.

6. The density of iron is 7.9 kg/l.

7. The density of an atomic nucleus is 2*1014 kg/l.

8. The density of air of 1.29 kg/l.
