Advice 1: How to convert kg to meters

It would seem, to translate kilograms to meters is absurd, however, some technical challenges needed. This translation requires knowledge of the linear density or ordinary density of the material.
How to convert kg to meters
You will need
  • knowledge of the linear density or the density of the material
Instruction
1
Units of mass are converted to units of length by using a physical quantity called linear density. In the SI system it has the dimension of kg/m As can be seen, this value differs from the usual density that expresses the mass per unit volume.
Linear density is used to characterize the thickness of threads, wires, fabrics, etc., as well as for the characterization of beams, rails, etc.
2
From the definition of linear density, it follows that for the translation of the mass in the length needed to divide the weight in kilograms per linear density in kg/m. thus we obtain the length in meters. In this length and will be given weight.
3
In that case, if we know the normal density with the dimension kg per cubic meter, to calculate the length of the material, which contains a mass, divide mass by density, and then to the cross-sectional area of the material. Thus, the formula for the length would be: l = V/S = (m/p*S) where m is the mass and V is the volume containing the mass, S is the cross - sectional area, p is the density.
4
In the simplest cases the cross section of the material will have either a round or rectangular shape. The area of the circular section is equal to pi*(R^2), where R is the radius of the cross section.
In the case of rectangular cross section, its area is equal to a*b, where a and b are the lengths of the sides of the section.
If the cross-section has a non-standard form, in each case, you need to find the area of the geometric shape that represents the cross-section.

Advice 2 : How to translate the volume-to-mass

Any object has mass and volume. And this is - an axiom. But, besides these two parameters, there is a third is density of the substance, which consists of a body (fluid). Knowing the density of the body quite easily translate volume to weight.
The formula for finding the mass of the body through its volume
You will need
  • Know from the table the density of a substance the exact density, which characterizes the substance of the original body.
Instruction
1
For clarity, it is necessary to consider an example. For example, given a concrete block, the volume of which is 4 m?. Now, turning to the table of densities of various substances shows that the density of concrete is 2300 kg/m?
Table of densities of various substances
2
Now, according to the formula for finding body mass, you can calculate:
m = 2300*4 = 9200 kg.
Thus, the mass of the concrete block with a volume of 4 m? will amount to 9.2 tons.
Note
Before doing the translation of volume to weight, you should always remember that the units must be converted to SI units: kilograms and meters. Therefore, if the original data specified units, other than those given above (e.g., grams, milligrams, centimeters, millimeters), it is necessary to translate them. For their translation we need to know:
1 kg = 1000 gr. = 1000000 mg.
1 m = 100 cm = 1000 mm.

Advice 3 : How to convert from kg to m

The number of tasks you need to know in a piece of material what length is the specified weight. In this task, knowing the pounds, you need to find the meters. This translation requires knowledge of the linear density or ordinary density of the material.

From the definition of linear density, it follows that for the translation of the mass in the length needed to divide the weight in kilograms per linear density in kg/m this gives you the length in meters. This length will contain this mass.
3
In that case, if you are aware of the normal density with the dimension kg per cubic meter, to calculate the length of the material, which contains weight, you must first obtain a volume of material, encompassing the mass. To do this, divide the mass by the density. Then, the resulting amount is divided by the cross sectional area of the material. Thus, the formula for the length would be: l = V/S = (m/p*S) where m is the mass and V is the volume containing the mass, S is the cross - sectional area, p is the density.

In trivial cases, the cross section of the material will have either a round or rectangular shape. The area of the circular section is equal to pi*(R^2), where R is the radius of the cross section.

In the case of rectangular cross section, its area is equal to a*b, where a and b are the lengths of the sides of the section.

If the cross section has an irregular shape, then you need to find the area of the geometric shape in cross-section.

Advice 4 : 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
How to convert kg to cubic meters
You will need
  • calculator
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
3
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 5 : How to convert kilograms to cubic meters

Kilograms and cubic meters are used to measure different physical quantities – mass and volume, respectively. To translate kilograms to cubic meters you must know the density of the substance, or at least, its name. If the substance is a liquid, it is still possible for the density close to the density of water – in this case, the translation process easier.

  • calculator, table of density of a substance

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.

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.
4
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.
