Whether you’re cooking, baking, meal prepping, or following a recipe, you may ask: How many cups are in a quart?

The answer depends on whether you’re using the U.S. customary system or the Imperial (UK) system.

Quick Answer

1 U.S. quart = 4 U.S. cups
1 Imperial (UK) quart = 4 Imperial cups

Both systems divide one quart into four cups. However, the actual size of a U.S. cup differs from the size of an Imperial cup, so the total liquid volume is different.

In this guide, you’ll learn the difference between U.S. and UK quarts, easy conversion formulas, practical examples, conversion charts, and answers to common kitchen questions.

Quick Conversion Chart

Measurement System	Quart	Cups
U.S. Customary	1 quart	4 cups
Imperial (UK)	1 quart	4 cups

Although both systems use four cups per quart, the cup sizes themselves are different.

Understanding Quarts and Cups

Both cups and quarts measure volume.

They’re commonly used for measuring:

Water
Milk
Soup
Juice
Broth
Flour (by volume)
Sugar
Cooking ingredients

A quart is simply a larger unit made up of four cups.

U.S. Quart vs. UK Quart

While both systems use the same relationship (4 cups = 1 quart), the measurements are not identical.

Unit	U.S.	Imperial (UK)
Quart	0.946 liters	1.137 liters
Cup	236.6 mL	284.1 mL

The Imperial quart is larger than the U.S. quart.

Quart to Cups Formula

To convert quarts into cups:

Cups = Quarts × 4

Examples:

1 quart = 4 cups
2 quarts = 8 cups
3 quarts = 12 cups
5 quarts = 20 cups

This formula works in both systems because each quart is divided into four cups.

Cups to Quarts Formula

To convert cups into quarts:

Quarts = Cups ÷ 4

Examples:

4 cups = 1 quart

Why Are U.S. and UK Quarts Different?

The Imperial quart is based on the larger British gallon introduced in 1824.

Although both contain four cups, the cups and quarts are physically larger in the Imperial system.
