Quart

A US quart is 946 ml, just under a liter, and equals 4 cups or 2 pints. The old British quart is larger. Here is how to convert quarts.

Also called Quarts, qt, Imperial quart.

A quart is a unit of volume used in American recipes. A US quart is 32 fluid ounces, 4 cups or 2 pints, and holds 946 ml, just under a liter. The imperial quart in older British recipes is 1.14 liters. The name means a quarter, because a quart is a quarter of a gallon.

How to do it

To check the size of a pot or dish you are not sure about:

  1. Fill a 1 liter jug, or a 4 cup measure, with water.
  2. Pour it into the pot. Count how many times it takes to fill the pot to about 2 cm (1 inch) below the rim.
  3. Each fill is about a quart.

How to use it

US measure Same as Metric
1 gallon 4 quarts 3.79 liters
1 quart 4 cups, 2 pints 946 ml
½ quart 2 cups, 1 pint 473 ml
¼ quart 1 cup 237 ml

For most cooking, you can treat 1 quart and 1 liter as the same. A liter is only about 5 percent more. A 1 liter carton of stock can stand in for a 1 quart one without changing the recipe.

American pots and baking dishes are sold by quart size. A 2 quart saucepan holds about 1.9 liters. A 5 to 6 quart Dutch oven holds about 5 liters. A stockpot is often 8 to 12 quarts, about 7.5 to 11 liters. A 2 quart baking dish is usually 20 x 20 cm (8 x 8 inches) or a bit larger.

Common mistakes

  • Using an imperial quart for an American recipe. It is about 20 percent larger.
  • Using a pot that is exactly the size of the recipe's volume. Leave room. Soup that makes 3 quarts needs a pot of 4 quarts or more so it does not boil over.
  • Mixing up the short forms. Qt is quart and pt is pint, which is half as much.

In recipes

You will see "1 quart chicken stock", "2 quarts water" and "a 4 quart pot". Brining recipes often say "1 gallon water" or "4 quarts water" with a set amount of salt. A dry quart, used for berries in the US, is a little larger than a liquid quart, about 1.1 liters.
