How to convert kilograms to cubic meters

Kilograms and cubic meters are used to measure different physical quantities - mass and volume, respectively. To convert kilograms to cubic meters, you need to know the density of the substance, or at least its name. If the substance is a liquid, then perhaps its density is close to the density of water - in this case, the transfer process is much simplified.

If the mass of the item is known, but it is necessary to determine its volume, then convert the specified number of kilograms to cubic meters. To do this, divide the mass of the object by its density. That is, use the formula:

Km³ = Kkg / P, where Km³ - the number of cubic meters, Kkg - the number of kilograms, P is the density of the substance, expressed in kg / m³.

Example.

What capacity tank will you need to store a ton (1000 kg) of gasoline?

Decision.

1000/750 = 1.33333

m³.

Rounding in this and similar cases is best done upwards, since the density of the substance is variable and depends on many factors (temperature, humidity, etc.).

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

If the density of the substance is unknown, then determine it from the corresponding tables of density of substances. Please note that the density of the substance should be indicated in kilograms per cubic meter (kg / m³). This unit of measure for the density of substances is standard and is found in most reference books. However, in practice one can often find another, non-systemic unit for measuring the density of liquid and granular substances - grams per liter (g / l). The numerical value of the density indicated in g / l can be used as kg / m³ without any coefficients. If the density of the substance is indicated in kilograms per liter (kg / l), then to convert it to kg / m³, divide this value by 1000.

More clearly, these rules can be written in the form of simple formulas:

Pkg / m³ = Pg / l, Pkg / m³ = Pkg / L / 1000, where: Pkg / m³, Pg / l, Pkg / l - substance density specified in kg / m³, g / l, kg / l, respectively.

If the substance for which you want to convert kilograms to cubic meters is water, then simply divide the number of kilograms by 1000. Use the same rule to determine the volumes of low-concentration solutions of substances. Of course, this should be a real mortar, and not such a consistency as, for example, "cement mortar".

If the item consists of an unknown substance or mixture of substances, then try to determine its density yourself. To do this, separate the part of the object, determine its mass and volume, and then divide the mass by volume. If the substance is a liquid, pour a portion of the liquid into a measuring container, determine its mass (net) and divide by volume. Similarly, you can determine the density of granular matter.
