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).

Milliliter (mL)

Metric (SI)Current unit

One thousandth of a liter, or exactly 1 cubic centimeter. Used for medicine, cooking and small containers.

Milliliters inherit everything from the liter, since the prefix simply means one thousandth. Because the liter is a cubic decimeter, a milliliter works out to exactly one cubic centimeter, a coincidence the metric system built in on purpose so that volume, length and mass interlock. One milliliter of water has a mass of about one gram, so a dosing syringe, a kitchen scale and a measuring jug can all be checked against one another.

Today milliliters dominate wherever small amounts must be measured precisely: medicine, flavorings, perfume, shampoo and the fine print on drink labels. Spelling is a mild regional split, with uppercase mL preferred in the United States, Canada and Australia and lowercase ml common in the UK and Europe. For scale, a US teaspoon is just under 5 mL, a US tablespoon is about 14.8 mL, and the US nutrition-label cup is exactly 240 mL, so one such cup is 240 of these tiny units.

1 milliliter = 0.001 liters (exactly).
