As with other measurement units used in the imperial system and USA, the pint used to be a common measure throughout Europe (differing in exact value from country to country) but was replaced in most of Europe with the metric system during the nineteenth century.

America adopted the British wine gallon (defined in 1707 as 231 cubic inches exactly (3 in × 7 in × 11 in)) as its basic liquid measure, from which the U.S. wet pint is derived, and the British corn gallon (⅛ of a standard “Winchester” bushel of corn, or 268.8 cubic inches) as its dry measure, from which the US dry pint is derived.
Many recipes published in the UK still provide ingredient quantities in imperial, where the pint is often used as a unit for larger liquid quantities. Most new recipes are now published in metric only with the "pint" being rounded to a convenient metric value.
In Australia and New Zealand, a subtle change was made in 1 pint milk bottles during the conversion from Imperial to metric in the 1970s. The height and diameter of the milk bottle remained unchanged, so that existing equipment for handling and storing such bottles was unaffected, but the shape was subtly adjusted to increase the capacity from 568 ml to 600 ml - a nice, round, metric measure. Such milk bottles are no longer officially referred to as pints. The pint glass in pubs in Australia (which is so called) remains closer to the standard Imperial pint, at 570 ml. A pint of beer in Australia or New Zealand is 570 ml, except in South Australia where a pint is 425 ml and 570 ml is called an imperial pint.
A 375 ml bottle of liquor in the US and the Canadian maritime provinces is sometimes referred to as a “pint”, harking back to the days when liquor came in actual US pints, quarts, and half-gallons.
In some regions of France, a standard 250 ml measure of beer is known as "a half", originally meaning a half pint.
