Cups to Quarts Converter

How to convert cups to quarts

1 cup = 0.25 quarts. To convert cups to quarts, divide by 4 (or multiply by 0.25). A US customary cup is 8 US fluid ounces, about 236.6 ml (nutrition labels use a rounded 240 ml). A US liquid quart is a quarter of a gallon, about 946.4 ml.

Worked examples

• 6 cups = 1.5 qt (6 ÷ 4)
• 12 cups = 3 qt (12 ÷ 4)
• 32 cups = 8 qt (32 ÷ 4)

Where this conversion comes up

Cups are used for US recipes and nutrition labels; quarts for motor oil, milk, stock and slow-cooker sizes. Divide by 4: 12 cups is 3 quarts and 32 cups is 8 quarts (2 gallons). Useful when a recipe scaled up in cups needs a pot size in quarts.

Quick estimate

Divide by 4; the remainder is extra cups.

Common mistakes

• Multiplying instead of dividing. A quart is larger than a cup, so the number of quarts must come out smaller: 6 cups = 1.5 qt.
• Mixing fluid ounces with weight ounces. A fluid ounce is a volume (29.57 ml); an ounce on a kitchen scale is a weight (28.35 g). A cup of flour is 8 fl oz by volume but only about 4.25 oz by weight.
• Using the imperial (UK) unit. This page uses US measures. An imperial gallon is 4.546 L (20% more than a US gallon), an imperial pint 568 ml and an imperial fluid ounce 28.41 ml.
