A pint is a unit of volume or capacity used to measure liquid, equal to one-eighth of a gallon. The pint is used in both the imperial and United States customary measurement systems, but the British imperial pint is about 20% larger than the American pint because the two systems are defined differently. The word "pint" comes from the Old French word "pinte" and perhaps ultimately from Vulgar Latin "pincta" meaning "painted," for marks painted on the side of a container to show capacity.

Some key facts about pints include:

• One pint is equal to half of a quart.
• One pint is equal to two cups.
• One US pint is equal to 473 milliliters, while one imperial pint is equal to 568 milliliters.

Pints are commonly used to measure liquid volume or capacity in both the US customary system and the British Imperial system of measurement.
