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 16 ounce American traditional pint. Under the Canada Weights and Measures Act, if asked for a "pint of beer", businesses should serve customers 0.568 litres of beer with an accuracy of 0.5%, and if asked for a "pinte de bière" they should serve them 1.136 litres. The Imperial system of measurement is no longer taught in Canadian schools, which leads to confusion when customers ask how big a drinking establishment's pints are. Servers and even managers may not know. To avoid legal issues, many drinking establishments are moving away from using the term "pint" and are selling "glasses" or "sleeves"
