The History of the US Gallon
The US gallon (231 cubic inches = 3.78541 L) descends from the English wine gallon, which colonists brought to America. When Britain reformed its measures with the Weights and Measures Act 1824, it redefined the gallon as the volume of 10 pounds of water (the imperial gallon, 4.546 L). America retained the pre-reform wine gallon. This permanent divergence explains why US and UK liquid measures — despite sharing names — are completely different quantities.
The History of the US Pint
The US pint (473 mL) differs significantly from the UK pint (568 mL) — a 20% difference that surprises travelers. A US pint of beer is 16 fl oz; a UK pint is 20 fl oz. Strawberries, blueberries, and cherry tomatoes are sold in pint containers at US farmers' markets. The pint's definition traces to the Latin pincta ('painted'), referring to a painted line on a measuring vessel.
