How to Convert Cups to Quarts

To convert a measurement in cups to a measurement in quarts, divide the volume by the following conversion ratio: 4 cups/quart.

Since one quart is equal to 4 cups, you can use this simple formula to convert:

quarts = cups ÷ 4

The volume in quarts is equal to the volume in cups divided by 4.

For example, here's how to convert 5 cups to quarts using the formula above.

quarts = (5 c ÷ 4) = 1.25 qt

How Many Quarts Are in a Cup?

There are 0.25 quarts in a cup, which is why we use this value in the formula above.

1 c = 0.25 qt

Cups and quarts are both units used to measure volume. Keep reading to learn more about each unit of measure.

What Is a Cup?

The cup is a unit of volume equal to 16 tablespoons or 8 fluid ounces. The cup should not be confused with the metric cup or the teacup, which are different units of volume.

One standard cup is equal to 236.588 milliliters, but for nutrition labeling, one cup is defined as 240 milliliters.[1] To further confuse things, a metric cup is equal to 250 mL, while in Japan, a cup is equivalent to only 200 mL.

The cup is a US customary unit of volume. Cups can be abbreviated as c, and are also sometimes abbreviated as C. For example, 1 cup can be written as 1 c or 1 C.

What Is a Quart?

The US liquid quart is a unit of fluid volume equal to one fourth of a gallon, two pints, or four cups.

The liquid quart should not be confused with the dry quart (US) or the imperial quart, which are different units. However, when someone refers to a volume in quarts, they typically mean the US liquid quart.

The quart is a US customary unit of volume. Quarts can be abbreviated as qt; for example, 1 quart can be written as 1 qt.
