The History of US vs. British Pints
Before the metric system and standardizations, unit definitions were linked to specific trades. The US adopted the British wine gallon (231 cubic inches) as its liquid volume standard, leading to a 16 fl oz pint.
In 1824, Great Britain unified its measurements under the Imperial system, basing its gallon on 10 pounds of water (277.42 cubic inches), resulting in a 20 fl oz pint.
