About these units
Kilderkin (kil)
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.

US Gallon (gal)
Exactly 231 cubic inches or 3.785411784 liters (128 US fluid ounces). About 17% smaller than the imperial gallon.
The US gallon is a survivor of English wine trade. Around 1706, a statute in Queen Anne's reign fixed the wine gallon at exactly 231 cubic inches, settling confusion among the competing gallons for wine, ale and corn. British colonies in North America used that wine gallon, and in 1824 Britain replaced all its gallons with a new imperial one while the United States kept the old measure. It was adopted as the legal US standard in 1836 and is still defined as exactly 231 cubic inches, or 3.785411784 liters.
That makes the US gallon about 17 percent smaller than the imperial gallon, a difference that explains why American and British fuel-economy figures cannot be compared directly. Everyday uses are milk jugs, paint cans and gasoline pumps. One gallon divides evenly into four quarts, eight pints, sixteen cups and 128 fluid ounces. A gallon of water weighs a little over 8 pounds, an easy figure to remember when loading a car with water jugs.
1 US gallon = 3.785411784 liters (exactly).
