bezdelnik — It is enough to know the density of the substance. It is measured in kg / meter cubic.

[33.8K] Cubometers can not be translated into tons, these are units of different physical quantities.

An excellent question, but the chosen best answer I was very sad. In the first place should be literacy.

In order to translate from cubic meters to tons, you need to know the density of the substance whose mass you want to calculate, since these two values are incommensurable and have different meaning, from a physical point of view.

The mass is considered to be such a formula:

m = ρv,

where m is the weight of the cargo

ρ - density

V - obsex

It is done very easily.

The only thing you need to know is the density of the substance.

where M is a mass that is measured in tons, P is the density of the substance, and V is the volume that is measured in cubic meters.

This task is not so difficult if you know the formula.

Suppose the density of any substance is calculated by the mass divided formula on the volume.

- The density (P) of substances can be found in the density table.

And since we are known as the volume, the mass can be calculated, by the equation (multiply the volume to the volume).

But there is a couple of nuances that you should not forget about.

In the density tables of substances, the density is represented either in kilograms on cubic meters, or in grams on cubic centimeters.

And we need a ton on the meter cubic.

The density of which is 8900 kg / meter (cubic). Thus, we need to be translated from this density to the necessary one.

And in fact, the question is not very correct. Therefore, it was difficult to answer it.)

A strange question, Cubes are a volume, tons are a mass. To translate Cuba in tons. You need to know what the proportion of the object you need. When the specific weight and volume (cubes) is known, the volume is multiplied by the proportion, we obtain a lot of (tons). Some of my friends are engaged in transportation, so they proceed from the specific weight of the cargo. If the specific weight of the cargo is less than a unit (floats in water), the calculation of the delivery cost goes into the cubes, if more than one (sinking in water), then in tons. **Rafail **[135K]

In order to know the volume to find a mass, you need to multiply the density, and not on the proportion. Density and share are completely different characteristics! The density is measured in kg / m ^ 3, and the proportion of n / m ^ 3. Outdated unit of specific gravity kg / m ^ 3 (kg - outdated unit weight kilogram-force), forget, they refused about 50 years ago from it.

If such a question, the physics teacher decides to check the knowledge of his students, then you need to answer -

In any way

In this case, one negative assessment will be less. Because ton is a mass unit, and cubic meters are a unit of volume.

But if proceeding from the assumption that he meant, it is better not to fantasize, but ask to clarify the issue in accordance with the physical units.

- Often, construction organizations are faced with the transfer of various units of measurement to other, for example, meters cube. in tons. To do this, it is enough to recall the formula chemical, where the mass of the substance is through the product of the volume on its density. The density table can be easily found on the Internet, and the volume is measured in the meters of cubic and already. Therefore, the calculation is carried out according to this formula:
- And when we find a mass, for example in kilograms, we translate it into tons. Visual disassembled example: we translate 9 m cube of compacted sand in tons:

So, nothing complicated.

Despite the fact that cubic meters are a unit of measurement of volume, and tons - weight measurements, to translate one thing to another. You need to know 2 things for this:

The density of which is 8900 kg / meter (cubic). Thus, we need to be translated from this density to the necessary one.

Density of material.

Although if you know the second point, this will be enough. So that you have not been looking for a long time, the densities of all the most used in the construction of materials are shown below.

As you can see, the density of steel-10 is 7856 kg per meter cubic. It turns out that in one meter of cubic 7,856 tons of steel. If you have a different volume (not 1 meter cubic), then simply multiply this value by 7,856.
