The litre (spelled litre in Commonwealth English[[1]] and liter in American English) is a unit of volume.

SymbolsEdit

There are two official symbols, the Latin letter el in both cases: l and L. The litre is not an SI unit but is accepted for use with the SI. The SI unit of volume is the cubic metre (m³).

Definitions and equivalents Edit

A litre is defined as a special name for a cubic decimetre (1 L = 1 dm³).

  • 1 L = 1000 cm³ (exactly)
  • 1000 L = 1 m³ (exactly)

SI prefixes applied to the litreEdit

The litre may be used with some SI prefixes.

Multiple Name Symbols Multiple Name Symbols

102 hectolitre hl hL 10–2 centilitre cl cL
103 kilolitre kl kL 10–3 millilitre ml mL

1015 petalitre Pl PL 10–15 femtolitre fl fL
1018 exalitre El EL 10–18 attolitre al aL

Other common metric equivalenciesEdit

  • 1 µL (microlitre) = 1 mm³ (cubic millimetre)
  • 1 mL (millilitre) = 1 cm³ (cubic centimetre)

ExplanationEdit

Litres are most commonly used for items measured by the capacity or size of their container (such as fluids and berries), whereas cubic metres (and derived units) are most commonly used for items measured either by their dimensions or their displacements. The litre is often also used in some calculated measurements, such as density (kg/L), allowing an easy comparison with the density of water.

One litre of water has a mass of almost exactly one kilogram. Similarly: 1 mL of water has about 1 g of mass; 1000 litres of water has about 1000 kg (1 tonne) of mass. This relationship is due to the history of the unit, but since 1964 it has not been part of the definition.

Symbol Edit

Originally, the only symbol for the litre was l (lowercase letter l), following the SI convention that only those unit symbols that abbreviate the name of a person start with a capital letter.
