Quart
From Wikipedia, the free encyclopedia
The quart[1] is an imperial and US customary unit of volume equal to a quarter of a gallon. Since gallons of various sizes have historically been in use, quarts of various sizes have also existed. Three of these quarts remain in current use, all approximately equal to one liter.
