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.

Exactly 4.54609 liters since 1985, and the reason UK and US fuel economy figures cannot be compared: it is 20% larger than the US gallon, so 40 mpg in Britain is about 33 mpg in America on the same car.
