About these units
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).

Hogshead (wine) (hhd)
63 US gallons (238.48 L), a quarter of a wine tun. A cask size for wine; tobacco hogsheads were a separate, larger size.
Philologists link the odd name to Germanic cask terms such as Dutch oxhooft and Danish oxehoved, literally an ox head, which English speakers may have bent into hogshead. An act of 1423 first tried to standardise the cask, but sizes still varied by product and place for centuries afterwards.
For wine the figure is 63 US wine gallons, or 52.5 imperial gallons, close to 238.5 litres (238.48 L as used here). It is a quarter of a tun and three quarters of a puncheon, and sits between the tierce at 42 gallons and the butt at 126. Other trades used different sizes: beer hogsheads of 54 gallons, fortified wines of 46 to 57 imperial gallons, and tobacco hogsheads of at least 550 litres.
Hogsheads carried far more than wine. Colonial Virginia shipped tobacco in them, British West Indies sugar averaged about 813 kilograms per cask, and Louisiana counted sugar by the hogshead for most of the nineteenth century. Whisky is typically matured in hogshead casks of about 250 litres.
1 hogshead (wine) = 238.4809424 liters (approximately).
