At first sight the phrase which is taken out in heading sounds absurdly as it is accepted to measure body weight in tons, and in cubic meters – volume. Nevertheless, such question or the return to it arises rather often. For example, producers sell the products in tons, and for transportation besides weight still goods dimensions are required.

1. It is necessary that tons corresponded to units of masses in an international system — SI. Therefore transfer tons to kilograms. For this purpose increase body weight for 1000. For example: 35 t =35·1000=35000 kg.
2. Performance of this action is fair for the metric system of measures. But it is necessary to remember existence of so-called long and short ton. Long, or English, the ton is most often used for determination of displacement of the vessel. For transfer of long ton to kilograms increase body weight by 1016.047 kg. Short, or American, the ton is applied in the USA and is transferred to kilograms by multiplication of weight by 907.185 kg.
3. In the reference book find substance density ρ of which the body is made. To make a right choice, consider a condition of this substance. So density of water, ice and water vapor is various. And charcoal density (layer) in more than seven times more coal density in bulk, and is almost twice more than density of coal dust. For example, ρ (charcoal) of =1450 kg/m³; ρ (coal dust) =750 kg/m³; bulk ρ (charcoal) of =200 kg/m³.
4. Use a formula V=m/ρ to determine body volume. Primer1 the t of coal occupies the volume of V=1000/200=5 m³, and 1 t of polyfoam at ρ=10 with kg/m³ - V=1000/10=100 m³. Thus, the cargo Gazelle with a capacity of body of 9 m³ and with a loading capacity up to 1.5 t for one flight will be able to transport all coal. And to deliver polyfoam, over 11 flights will be required.
