Let’s start with the basics. A quart comes from the English unit of measurement, “quarter gallon.” That’s right! Another unit of measurement- a gallon!Most of the time, when a quart is referred to, especially in the culinary world, it is referring to a liquid quart. Conversions can be confusing enough, so instead of differentiating between a liquid quart and a dry quart, which gets into bushels, we will focus on liquid quarts.

1 US liquid quart is equal to ¼ gallon, 2 pints, 4 cups, and 32 ounces. Note that a dry quart is equal to 4.6546 cups, which is important when doing conversions for any dry ingredient.

Quarts and cups are commonly used measurement units for liquids.
 While the world went its metric way, the United States retained a set of different measurement units, some of them useful, some of them not so much. Quarts are a measurement unit for volume, particularly useful when measuring liquids.
