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.
