Cubic metre
SI unit of volume
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 stère, 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 °C) and standard atmospheric pressure (101.325 kPa) has a mass of 1000 kg, or one tonne, which makes its maximum density at 101.325 kPa 1 Mg/m3. At 0 °C, the freezing point of water, a cubic metre of water has slightly less mass, 999.85 kilograms.
The public source identifies “Cubic metre” as sI unit of volume. This brief keeps that definition visible, then builds a research path around Cubic, metre and unit.
Why this record matters
A short description can identify a subject without explaining its stakes. For “Cubic metre”, the useful work is to connect “sI unit of volume” to the records capable of establishing context and consequence.
The citation trail is more important than the brevity of the summary: it shows where individual claims can be examined in context. The source revision retrieved here is dated Jun 7, 2026. The linked authority identifier is Q25517. None of the 0 selected statements returned an explicit reference. The first chronological checks are 1000.
The absence of detail may reflect summary conventions rather than a lack of surviving documentation. The lead is largely declarative, so disagreement and counter-evidence require a deliberate search beyond the opening account. Authority statements aid reconciliation but still require their own references, qualifiers and ranks to be checked.
