How it works
In the US Customary measurement system, quarts and cups are related by a simple factor of 4:
Standard Liquid Conversion
1 Quart (qt) = 4 Cups (c)
Conversion Formula
Multiply quarts by 4 to get cups. Divide cups by 4 to get quarts.
Dry Quarts vs. Liquid Quarts
In the United States, there are actually two different definitions of a quart:
- US Liquid Quart: Used for fluids like water, milk, and juice. It is equal to exactly 32 fluid ounces (946.35 mL).
- US Dry Quart: Used for dry agricultural commodities like berries and grain. It is slightly larger, equaling approximately 37.24 fluid ounces (1101.22 mL).
For kitchen cooking and baking, standard measuring cups and liquid quarts are always aligned under the liquid conversion standard (1 quart = 4 cups).
US Customary vs. Imperial Volumes
The British Imperial system defines a quart differently. An Imperial quart is 40 Imperial fluid ounces, while an Imperial cup is 10 Imperial fluid ounces, meaning there are still exactly 4 Imperial cups in an Imperial quart.
However, if you mix standards—such as measuring an Imperial quart using standard US Customary cups (which hold 8 US fluid ounces)—you will need approximately 4.546 cups to fill one Imperial quart.
