The litre (spelled liter in American English and German) is a metric unit of volume. The litre is not an SI unit, but (along with units such as hours and days) is listed as one of the "units outside the SI that are accepted for use with the SI." The SI unit of volume is the cubic metre (m³).

This unit is used in North America for crude oil or other petroleum products. Elsewhere oil is more commonly measured in cubic metres (m³) and less commonly in tonnes. The Standard Oil Company shipped its oil in barrels that always contained exactly 42 U.S. gallons.
