QUARTS

The quart^[1] is a unit of volume (for either the imperial or US customary unit of measure) equal to a quarter of a gallon, two pints, or four cups. Since gallons of various sizes have historically been in use, quarts of various sizes have also existed; see gallon for further discussion. Three of these kinds of quarts remain in current use, all approximately equal to one litre.

[edit] Definitions and Equivalencies

United States liquid quart

All traditional U.S. length and volume measures have been legally standardized for commerce using the definition of 1 yard being exactly equal to 0.9144 meter. From this definition is derived the metric equivalencies for inches, feet, and miles; as well as area measures; and measures of volume. The US liquid quart equals 57.75 cubic inches, which is exactly equal to 0.946352946 litres.^[2][3]
