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
- 8 cups = 2 quarts
- 12 cups = 3 quarts
- 16 cups = 4 quarts

Why Are U.S. and UK Quarts Different?
The U.S. customary and Imperial systems developed separately.
- The U.S. quart is based on the historical U.S. gallon.
- 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.
Kitchen Tips for Accurate Measuring
- Use liquid measuring cups for liquids.
- Place measuring cups on a level surface.
- Read measurements at eye level.
- Verify whether a recipe uses U.S. or UK measurements.
- For international recipes, metric measurements may provide greater accuracy.
