Cubic metre

''CM3 redirects here. If you were looking for the 3rd game in the Cooking Mama series, abbreviated as CM3, see here.

The cubic metre (US spelling: cubic meter, symbol: m³) is the SI derived unit of volume. 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 stère. Another alternative name, not widely used any more, is the kilolitre.

A cubic metre of pure water at the temperature of maximum density (3.98 °C) and standard atmospheric pressure (101.325 kPa) has a mass of 1000 kg, or one tonne. At 0 °C, the freezing point of water, it is slightly less, 999.972 kilograms.

It is sometimes abbreviated to cu m, m3, m^3 or m**3 when superscript characters or markup are not available/accessible (i.e. in some typewritten documents and postings in Usenet newsgroups).

Abbreviated CBM in the freight business and MTQ (or numeric code 49) in international trade.
