About these units

Kilderkin (kil)

Imperial (British)Traditional unit (still used in some regions)

18 imperial gallons (81.8 L), two firkins or half a UK beer barrel.

Dutch kinderkin, a small cask, is the origin of this word, and a kilderkin holds 18 imperial gallons, exactly 81.82962 liters, or two firkins, half a barrel. Nominally that is 144 pints, though a real cask yields fewer because of sediment and other unsellable beer.

Its size has shifted with the gallon. Before 1824 the beer kilderkin was always 18 ale or beer gallons, but that gallon itself changed: kilderkins held 16 gallons (73.94 L) from the mid fifteenth century, 17 gallons (78.56 L) from 1688 and 18 gallons (83.18 L) from 1803. The Weights and Measures Act 1824 replaced these with the imperial gallon and brought the cask to its present volume. A wine kilderkin was far smaller, around 13 imperial gallons. The Campaign for Real Ale uses the kilderkin as its yardstick for planning beer quantities at festivals and in internal accounts.

1 kilderkin = 81.82962 liters (exactly).

Liter (L)

Metric (SI)Current unit

One cubic decimeter (1,000 cm³). The everyday metric unit of volume for drinks, fuel and cooking.

The liter was born in revolutionary France. In 1795 it was introduced as a republican unit and defined as one cubic decimeter, while the gram was tied to a cubic centimeter of water. The name comes from the older French litron, itself descended from a Byzantine Greek unit of weight, not volume. A small revision of the decimeter in 1798 left the first liter about 1.000974 of today's cubic decimeter, and in 1879 the international metric authorities adopted the liter with the symbol l.

The liter then took a strange detour. In 1901 it was redefined as the space taken up by one kilogram of pure water at its densest, which made it about 1.000028 cubic decimeters, and that muddled definition lasted until 1964, when it was restored to exactly one cubic decimeter. A capital L was added as an alternative symbol in 1979 because a lowercase l is easy to mistake for the digit 1, and NIST says L is the symbol to use in the United States. A liter of water is close to a kilogram, which is why a one-liter bottle feels like a kilo in the hand.

The liter is the reference unit for volume on this site.
