The '''quart''' (symbol: '''qt''')<ref>{{cite book |title=BS350:Part 1:1974 Conversion factors and tables Part 1. Basis of tables. Conversion factors |date=1974 |publisher=British Standards Institution |pages=10, 86}}</ref> 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 {{nowrap|'''imperial quart'''}} of the [[imperial unit|British imperial system]]. All are roughly equal to one [[liter]]. It is divided into two [[pint]]s or (in the US) four [[cup (unit)|cup]]s. Historically, the size of a quart has varied with the different values of gallons over time, and in the case of the dry quart, in reference to different commodities.
