Pint a limited extent in Commonwealth nations. In the United States, two pints are used: a liquid pint (≈ 473 ml) and a less-common dry pint (≈ 551 ml). Each of these pints is one-eighth of its respective gallon, but the gallons differ. This difference dates back to 1824, when the British Weights and Measures Act standardised various liquid measures throughout the British Empire, while the United States continued to use the earlier English measure. The imperial pint consists of 20 imperial fluid ounces and the US liquid pint is 16 US fluid ounces, making the imperial fluid ounce about 4%
Pint all the various gallons with a new imperial gallon based on ten pounds of distilled water at (277.42 cubic inches), from which the current UK pint is derived. The various Canadian provinces continued to use the Queen Anne Winchester wine gallon as a basis for their pint until 1873, well after Britain adopted the imperial system in 1824. This made the Canadian pint compatible with the American pint, but after 1824 it was incompatible with the British pint. The traditional French "pinte" used in Lower Canada (Quebec) was twice the size of the traditional English "pint" used in Upper Canada
