✔ Updated · conversion charts: liquid, dry + UK
A quart shows up in soup, stock and canning recipes, and converting it to ounces is easy once you know one number. Here it is, with charts for every common amount.
There are 32 fluid ounces in 1 US liquid quart. That's the same as 4 cups, 2 pints or about 946 milliliters. Half a quart is 16 fl oz, and a quarter of a quart is 8 fl oz (1 cup). A US dry quart is a little larger, at about 37.2 fl oz, and a UK imperial quart is 40 imperial fluid ounces.
- Quarts to ounces: multiply the quarts by 32.
- Ounces to quarts: divide the fluid ounces by 32.
- Weight is different: a quart of water weighs about 33.4 oz (2.1 pounds), but a quart of flour weighs only about 17 oz.

How to Convert Quarts and Ounces
- Quarts to fluid ounces: multiply by 32. Example: 2.5 quarts x 32 = 80 fl oz.
- Fluid ounces to quarts: divide by 32. Example: 48 fl oz / 32 = 1.5 quarts.
- Quarts to cups: multiply by 4. Each cup is 8 fl oz.
- Quarts to milliliters: multiply by 946. A quart is just under 1 liter (1 liter is about 33.8 fl oz).
- Quarts to gallons: divide by 4, since 4 quarts make 1 gallon (128 fl oz).
Liquid Quart vs Dry Quart vs UK Quart
Not every quart is the same size. In cooking, "quart" almost always means the US liquid quart. The US dry quart is used for produce like berries and cherry tomatoes, and the imperial quart is used in older British recipes.
| Quart | US fluid ounces | Milliliters | Used for |
|---|---|---|---|
| US liquid quart | 32 fl oz | 946 ml | Milk, broth, cream, recipes, deli containers |
| US dry quart | About 37.2 fl oz | 1,101 ml | Berries, cherry tomatoes and other produce at markets |
| UK imperial quart | About 38.4 US fl oz (40 imperial fl oz) | 1,137 ml | Older British and Irish recipes |
Fluid Ounces vs Weight Ounces
A fluid ounce measures volume (how much space something takes up). A regular ounce measures weight. They only line up for water and liquids like it: a quart of water, milk or broth weighs about 33 to 34 ounces, which is close to its 32 fluid ounces. For a liquid example in pounds, see how much a gallon of milk weighs.
For dry ingredients, the weight of a quart varies a lot, so weigh them when accuracy matters. Approximate weights for 1 quart (4 cups):
- Water or milk: about 33.4 to 34.5 oz (2.1 pounds)
- Honey: about 48 oz (3 pounds)
- Granulated sugar: about 28 oz
- All-purpose flour: about 17 oz
- Uncooked white rice: about 28 oz
- Fresh blueberries: about 20 to 22 oz
Everyday Things That Hold a Quart
- A quart carton of milk, half-and-half or broth: 32 fl oz.
- A quart mason jar and a quart deli container: 32 fl oz.
- A quart-size freezer bag: about 1 quart, though fill it only about 3/4 full with soup or stock so it can expand and seal.
- Standard 16.9 fl oz water bottles: about 1.9 bottles make a quart.
- A 64 oz pitcher or jug: 2 quarts (half a gallon).
Common Mistakes
- Mixing up liquid and dry quarts. A dry quart of berries holds about 16% more than a liquid quart.
- Using a dry cup for liquids. Measure liquids in a clear measuring jug at eye level; dry cups make it easy to spill or under-fill.
- Assuming ounces on a package mean fluid ounces. A 32 oz bag of flour or sugar is weight, not a quart by volume.
- Following a UK recipe with US cups. An imperial quart and pint are about 20% larger than US ones, so liquids can come up short.
Frequently Asked Questions
How many ounces are in a quart?
There are 32 fluid ounces in 1 US liquid quart. That equals 4 cups, 2 pints or about 946 milliliters. A US dry quart holds about 37.2 fluid ounces, and a UK imperial quart holds 40 imperial fluid ounces, about 38.4 US fluid ounces.
Is 32 oz the same as 1 quart?
Yes. 32 US fluid ounces equals exactly 1 US liquid quart, so a 32 oz container holds a quart. If the 32 oz on a package is weight, like a bag of flour, it isn't the same as a quart by volume.
How many 8 oz cups are in a quart?
There are four 8 ounce cups in a quart, because 4 x 8 = 32 fluid ounces. Two quarts hold 8 cups, and a gallon holds 16 cups.
How many quarts is 64 oz?
64 fluid ounces equals 2 quarts, which is also half a gallon or 8 cups. To convert any number of fluid ounces to quarts, divide by 32.
Is a quart bigger than a liter?
No. A US liquid quart is about 946 milliliters, slightly smaller than a liter (1,000 ml, about 33.8 fluid ounces). A UK imperial quart, at about 1,137 ml, is bigger than a liter.
