A British pint is a fifth larger than an American one
The imperial pint is 568.26125 ml and the US liquid pint is 473.176473 ml, so a pint of beer in London is 20% more beer than a pint in New York. Both are called a pint and both are legal measures. The gap comes from the gallons they divide: the imperial gallon is 4.54609 liters against the US gallon’s 3.785411784, and every fraction below them inherits the difference.
NIST Handbook 44, Appendix C — general tables of units of measurement
What is a US pint?
Two US cups, about 473 ml. A UK pint is 568 ml — a fifth larger.
What is an imperial pint?
An eighth of an imperial gallon, 568.26125 ml exactly, and still the legal measure for draught beer and doorstep milk in the UK. A US pint is 473 ml, which is why a British pint glass holds noticeably more.
How many imperial pints are in a US pint?
One US pint is 0.83267418 imperial pints. Going the other way, one imperial pint is 1.2009499 US pints. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
