The quart (symbol: qt) [1] is a unit of volume equal to a quarter of a gallon. Three kinds of quarts are currently used: the liquid quart and dry quart of the US customary system and the imperial quart of the British imperial system. All are roughly equal to one liter. It is divided into two pints or (in the US) four cups. Historically, the ...
Volume may be measured either in terms of units of cubic length or with specific volume units. The units of cubic length (the cubic inch, cubic foot, cubic mile, etc.) are the same in the imperial and US customary systems, but they differ in their specific units of volume (the bushel, gallon, fluid ounce, etc.).

The United States customary system developed from English units that were in use in the British Empire before the U.S. became an independent country. The United Kingdom's system of measures evolved by 1824 to create the imperial system (with imperial units ), which was officially adopted in 1826, changing the definitions of some of its units.
The US Customary system of units was developed and used in the United States after the American Revolution, based on a subset of the English units used in the Thirteen Colonies; it is the predominant system of units in the United States and in U.S. territories (except for Puerto Rico and Guam, where the metric system, which was introduced when ...
the US liquid gallon (US gal), defined as 231 cubic inches (exactly 3.785 411 784 L), [1] which is used in the United States and some Latin American and Caribbean countries; and; the US dry gallon, defined as 1 ⁄ 8 US bushel (exactly 4.404 883 770 86 L). There are two pints in a quart and four quarts in a gallon. Different sizes of pints ...
A US fluid ounce is 1 / 16 of a US pint (about 1·04 UK fluid ounces or 29.6 mL); a UK fluid ounce is 1 / 20 of a UK pint (about 0·96 US fluid ounce or 28.4 mL). On a larger scale, perhaps for institutional cookery, a UK gallon is 8 UK pints (160 UK fluid ounces; about 1·2 US gallons or 4.546 litres), whereas the US gallon is ...
A US fluid ounce (fl oz), about 29.6 millilitres (ml), is slightly larger than the imperial fluid ounce (about 28.4 ml). However, as there are 16 US fl oz to a US pint and 20 imp fl oz per imperial pint, the imperial pint is about 20% larger. The same is true of quarts, gallons, etc.; six US gallons are a little less than five imperial gallons.
