How Many Cups in a Quart?

One US quart equals exactly 4 US cups. To convert quarts to cups, multiply the quart value by 4. The quart is a common measurement for larger quantities of liquids in American cooking — broths and stocks are sold by the quart, many soup and stew recipes are measured in quarts, and punch and beverage recipes for parties often call for quarts. Understanding this four-to-one relationship helps you accurately scale recipes, figure out how many containers of broth to buy, and convert between recipe measurements and the markings on your liquid measuring cup.

How to Convert Quart (US) to Cup (US)

  1. To convert quarts to cups, multiply the quart value by 4.
  2. To convert cups to quarts, divide the cup value by 4.
  3. The result is exact — no rounding needed.
  4. Remember the full sequence: 1 quart = 4 cups = 2 pints = 32 fluid ounces = 946 ml.
  5. A quart is one-quarter of a gallon, which is where the name "quart" originates.

Real-World Examples

A soup recipe calls for 2 quarts of chicken stock. How many cups is that?
2 x 4 = 8 cups. You would need two 32 oz (1 quart) cartons of stock.
You have 6 cups of homemade broth. How many quarts is that?
6 / 4 = 1.5 quarts. You could fill one quart container and one pint container for storage.
A punch recipe for a party calls for 3 quarts of fruit juice.
3 x 4 = 12 cups. That is 96 fluid ounces, or three 32-oz bottles of juice.
An ice cream maker has a 1.5 quart capacity. How many cups does it produce?
1.5 x 4 = 6 cups of ice cream per batch. That is roughly 12 half-cup servings.
You want to can 20 cups of tomato sauce. How many quart jars do you need?
20 / 4 = 5 quart jars, filled completely. Buy 6 jars to allow for headspace and spillage.

History of Quart (US) and Cup (US)

The word "quart" comes from the Latin "quartus," meaning fourth, because a quart is one-quarter of a gallon. The quart has been used in England since at least the 13th century, when it was defined by royal decree as a specific fraction of a gallon. Like other US customary units, the American quart diverged from the British Imperial quart in the 19th century. The US liquid quart is 946 ml, while the Imperial quart is 1,136 ml — a difference of about 20%. This means British recipes calling for quarts need adjustment when followed with US measuring cups.

Common Mistakes to Avoid

  • Confusing quarts with liters. A US quart (946 ml) is about 5% smaller than a liter (1,000 ml). Using a liter where a recipe calls for a quart means adding about 2 extra tablespoons of liquid — noticeable in baking but usually fine for soups and stews.
  • Confusing US quarts with Imperial quarts. An Imperial quart (1,136 ml) is about 20% larger than a US quart. Using a British recipe with US measurements without adjusting for this difference will leave you short on liquid.
  • Forgetting the dry quart exists. A US dry quart (1,101 ml) is larger than a liquid quart (946 ml). Produce is sometimes sold by the dry quart, but recipes always mean the liquid quart unless specifically stated otherwise.

Frequently Asked Questions

How many quarts are in a gallon?
There are exactly 4 quarts in a gallon. So 1 gallon = 4 quarts = 8 pints = 16 cups = 128 fluid ounces.
Is a quart close enough to a liter that I can substitute?
For most cooking purposes, yes. A US quart is 946 ml and a liter is 1,000 ml — the difference is about 54 ml (less than 1/4 cup). For soups, stews, and sauces, this difference is negligible. For baking, measure precisely.
Why do American recipes use quarts instead of liters?
The US customary system predates the widespread adoption of the metric system and remains the standard in American kitchens. Quarts fit neatly into the US volume hierarchy (cups, pints, quarts, gallons), all related by factors of 2. Stock, broth, and other liquids are still packaged and sold by the quart in the US.
How do I measure a quart if I only have a cup measure?
Fill your measuring cup 4 times. Each cup is 8 fl oz, so 4 cups equals 32 fl oz, which is exactly 1 quart. Alternatively, fill it twice for half a quart (1 pint).
Quick Tip

When buying broth or stock at the grocery store, remember that the standard carton is 32 fl oz, which is exactly 1 quart or 4 cups. If your recipe calls for 6 cups of broth, you need one and a half cartons. Knowing this saves you from standing in the aisle doing math on your phone.
