Quart

The quart (abbreviation: qt) is an English unit of volume equal to a quarter gallon. It is divided into two pints or (in the US) four cups. Historically, the exact size of the quart has varied with the different values of gallons over time and in reference to different commodities. Presently, three kinds of quarts remain in use: the liquid quart and dry quart of the US customary system and the imperial quartBritish imperial system. All are roughly equal to one litre. 


Gallon (US)

A gallon is a unit of volume specifically regarding liquid capacity in both the US customary and imperial systems of measurement. The US gallon is defined as 231 cubic inches (3.785 litres). In contrast, the imperial gallon, which is used in the United Kingdom, Canada, and some Caribbean nations, is defined as 4.54609 litres. In both systems, the gallon is divided into four quarts. Quarts are then divided into two pints and pints are divided into two cups. A cup is comprised of two gills, making one gallon equal four quarts, eight pints, sixteen cups, or thirty-two gills. Further differentiating the US and the imperial gallon, a US gill is divided into four fluid ounces, while an imperial gallon is divided into five. A US fluid ounce is therefore 1/128 of a US gallon while an imperial fluid ounce is 1/160 of an imperial gallon.
