<P> The imperial pint ( ≈ 568 ml ) is used in the United Kingdom and Ireland and to 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 and the imperial pint is about 20 % larger than the US liquid pint . 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 measures . 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 % smaller than the US fluid ounce . </P>
