Explanation

A quart is a unit used to measure something liquid, like milk or paint. There are four quarts in a gallon. A quart of paint may be all you need to spruce up your front door, and your cake recipe might call for a quart of buttermilk. In both cases, you're using the equivalent of four liquid cups or one-fourth of a gallon. The word dates from the 14th century, from a Latin root, quartus, which means "the fourth part."
