The litre is unit of volume accepted for use with the SI metric system, with size of 0.001 cubic metres or 1,000 cubic centimetres.

SI Metric

The litre is an SI accepted unit (See table 6 of the SI Brochure) of volume equal to 1 cubic decimetre or 1/1000th of a cubic metre.

Metre

Formal: L,l

The abbreviations Lt, lt, Ltr and ltr are also sometimes seen.

The litre (American spelling: liter) can be used with all the SI standard prefixes. Unlike the cubic volume units the prefixes have their standard factor when used with the litre.

The litre was one of the original metric units defined in 1795 in France as part of the new Republic's system of measurements. It was originally defined as 1 cubic decimetre.

Following this in 1901 at the 3rd CGPM conference it was redefined as the volume of 1 kilogram of pure water at maximum density (3.98°C) and standard atmospheric pressure (1atm).

The 1901 definition was dropped in 1964 at the 12th CGPM conference and the the litre once again became 1 cubic decimetre.

Litres are often used for measuring water (1kg of water is very close to 1 litre), beer, gasoline/petrol, paint and other liquids in everyday use.

BIPM: SI accepted unit (See Table 6)

The litre is in general use everywhere except the United States, Liberia and dependent territories. In other English speaking countries the use of litre is not universal, with Imperial measurements still being used for some commodities (e.g. the pint of beer or milk) and by some people.

- 1 litre = 1,000,000 cubic millimetres
- 1 litre = 1,000 cubic centimetres
- 1 litre = 1 cubic decimetre
- 1 litre = 0.001 cubic metres
- 1 litre = 0.000001 cubic decametres
- 1 litre = 0.000000001 cubic hectometres
- 1 litre = 0.000000000001 cubic kilometres

- 1 cubic millimetre = 0.000001 litres
- 1 cubic centimetre = 0.001 litres
- 1 cubic decimetre = 1 litre
- 1 cubic metre = 1,000 litres
- 1 cubic decametre = 1,000,000 litres
- 1 cubic hectometre = 1,000,000,000 litres
- 1 cubic kilometre = 1,000,000,000,000 litres

The Imperial (UK) pint is a measure of liquid volume equal to 1/8th of a gallon. UK pints are most commonly associated with milk and beer.

Imperial

The Imperial (UK) pint is defined as 1/8th of an Imperial gallon.

Imperial Gallon

Formal: pt

The abbreviation p is also sometimes seen. When both UK and US pints are likely to be seen together UK pt or Imp pt and US pt are used.

The UK pint is 1/8th of a UK gallon and is equal to 20 fluid ounces (as opposed to the US pint of 16 fluid ounces). Imperial liquid volume measures have their roots in the Weights and Measures act of 1824 which defined the UK gallon based on the ale gallon in use at the time (the US gallon is based on the wine gallon).

In 1985 a new weights and measures act redefined the gallon in terms of metric measures, so that the UK pint is now exactly 0.56826125 litres.

UK Weights & Measures Act 1824

Imperial pints are no longer in use apart from some special cases including milk sold in returnable bottles, beer and cider. UK legislation has enacted the right to sell beer and cider in Imperial pints in perpetuity.

- 1 imperial pint = 20 imperial fluid ounces
- 1 imperial pint = 4 imperial gills
- 1 imperial pint = 0.5 imperial quarts
- 1 imperial pint = 0.125 imperial gallons

- 1 imperial fluid ounce = 0.05 imperial pints
- 1 imperial gill = 0.25 imperial pints
- 1 imperial quart = 2 imperial pints
- 1 imperial gallon = 8 imperial pints
