| CUBIC METRE | The cubic metre, or cubic meter (in American English) is the SI derived unit of volume. Its SI 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. | |
| Conversions | 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. | |
| Multiples | Cubic decametre: the volume of a cube of side length one decametre (10 m) equal to a megalitre 1 dam3 = 1000 m3 = 1 ML |
| Cubic hectometre: the volume of a cube of side length one hectometre (100 m) equal to a gigalitre in civil engineering abbreviated MCM for million cubic metres 1 hm3 = 1000000 m3 = 1 GL | Cubic kilometre: the volume of a cube of side length one kilometre (1000 m) equal to a teralitre 1 km3 = 1000000000 m3 = 1 TL (810713.19 acre-feet; 0.239913 cubic miles) |
| Submultiples | Cubic decimetre the volume of a cube of side length one decimetre (0.1 m) equal to a litre 1 dm3 = 0.001 m3 = 1 L |
| Cubic millimetre | the volume of a cube of side length one millimetre (0.001 m) equal to a microlitre 1 mm3 = 0.000000001 m3 = 10−9 m3 = 1 µL |
