Any unit of length gives a corresponding unit of volume, namely the volume of a cube whose side has the given length. For example, a cubic centimetre(cm3) would be the volume of a cube whose sides are one centimetre (1 cm) in length.
In the International System of Units (SI), the standard unit of volume is the cubic metre (m3). The metric system also includes the litre (L) as a unit of volume, where one litre is the volume of a 10-centimetre cube. Thus
- 1 litre = (10 cm)3 = 1000 cubic centimetres = 0.001 cubic metres,
so
- 1 cubic metre = 1000 litres.
Small amounts of liquid are often measured in millilitres, where
- 1 millilitre = 0.001 litres = 1 cubic centimetre.
Various other traditional units of volume are also popular, including the cubic inch, the cubic foot, the cubic mile, the teaspoon, the tablespoon, the fluid ounce, the fluid dram, the gill, the pint, the quart, the gallon, the minim, the barrel, the cord, the peck, the bushel, and the hogshead.
