(in Commonwealth English and international spelling as used by the International Bureau of Weights and Measures)
or cubic meter (in American English)
.
-the [cubic meter] is the ‘unit’ of ‘volume’ in the ‘International System of Units’ (SI)-
.
Its symbol is m3.[1]
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, still sometimes used for dry measure (for instance, in reference to wood).
Another alternative name, no longer widely used, was the kilolitre.
Conversions[edit]
Some SI units of volume to scale and approximate corresponding mass of water
1 cubic metre = 1000 litres (exactly)
≈ 35.3 cubic feet
≈ 1.31 cubic yards
≈ 6.29 oil barrels
≈ 220 imperial gallons
≈ 264 US fluid gallons
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, a cubic metre of water has slightly less mass, 999.972 kilograms.
A cubic metre is sometimes abbreviated to m^3, M3, m**3, cu m, m3, CBM, cbm when superscript characters or markup cannot be used (e.g. in some typewritten documents and postings in Usenet newsgroups). The “cubic metre” symbol is encoded by Unicode at code point U+33A5 ㎥ SQUARE M CUBED.[4]

^ From 1901 to 1964 the litre was defined as the volume of one kilogram of pure water at 4°C and 760 millimetres of mercury pressure. During this time, a litre was about 1.000028 dm3. In 1964 the original definition was reverted to.
