Cubic metre

The cubic metre (in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures) or cubic meter (in American English) is the unit of volume in the International System of Units (SI). Its symbol is m3. It is the volume of a cube with edges one metre in length. An alternative name, which allowed a different usage with metric prefixes, was the stÃÂ¨re, still sometimes used for dry measure (for instance, in reference to wood). Another alternative name, no longer widely used, was the kilolitre. The acronym CBM is in common use to describe a cubic metre.

Conversions

A cubic metre of pure water at the temperature of maximum density (3.983 ÃÂ°C) and standard atmospheric pressure (101.325 kPa) has a mass of , or one tonne, which makes its maximum density at 101.325 kPa 1 Mg/m3. At 0 ÃÂ°C, the freezing point of water, a cubic metre of water has slightly less mass, 999.85 kilograms.
