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).

Puncheon (pun)
84 US gallons (318 L), two tierces. A cask for rum and wine.
Richard III is named as having set the wine puncheon at 84 gallons, a size that works out to about 318 litres (317.97 L as used here) in US wine gallons, or 70 imperial gallons. Wikipedia notes the US puncheon is four thirds of a hogshead, so it also equals two tierces.
Unlike the neat wine figure, the puncheon was a loose term in practice. British usage for beer, wine and spirits placed it anywhere between 70 and 120 imperial gallons, roughly 318 to 546 litres, so a puncheon of rum could be markedly larger than one of wine. Any stated size therefore depends on the trade and the period.
Within the English wine ladder it falls between the 63 gallon hogshead and the 126 gallon butt, a third of a tun. The ratios are exact in US gallons: it equals two tierces and four thirds of a hogshead.
1 puncheon = 317.9745899 liters (approximately).
