Quarts to ounces formula
fl oz = qt × 32 (US)
- Take the volume in US quarts.
- Multiply by
32, because one US liquid quart holds 2 pints × 16 = 32 US fluid ounces.
Example: a 2.5 qt pot holds 2.5 × 32 = 80 US fl oz. Reverse: qt = fl oz ÷ 32, so a 64 fl oz bottle is 64 ÷ 32 = 2 qt.
UK imperial: fl oz = qt × 40. The imperial quart is 2 imperial pints of 20 fl oz each, so 1.5 imperial quarts = 60 imperial fl oz.
Switch "Measurement system" above to UK to convert imperial quarts; the tables update too.

US vs UK quarts and fluid ounces
Both systems split a gallon into 4 quarts and a quart into 2 pints, but the gallons are different sizes and so are the fluid ounces. The US liquid quart is 946.35 mL and the imperial quart is 1,136.52 mL, about 20% bigger. On top of that, a US fluid ounce (29.57 mL) is about 4% larger than an imperial fluid ounce (28.41 mL). Mixing the two systems is the most common source of error in old British recipes and imported product labels.
| US customary | UK imperial | |
|---|---|---|
| 1 quart | 946.353 mL | 1,136.5225 mL |
| 1 fluid ounce | 29.5735 mL | 28.4131 mL |
| Fluid ounces in 1 quart | 32 | 40 |
| 1 quart in the other system's fl oz | 33.31 imperial fl oz | 38.43 US fl oz |
| Pints in 1 quart | 2 (16 fl oz each) | 2 (20 fl oz each) |

Tips
- Fluid ounces are volume, ounces are weight. A US quart of water holds 32 fl oz but weighs about 33.4 oz (2.09 lb). Flour, sugar and other dry goods weigh far less or more per quart, so use a scale for those.
- Dry quarts are different. Produce such as berries is sometimes sold by the US dry quart, which is 1.101 L (about 37.2 US fl oz of volume). This converter uses liquid quarts.
- A "quart" deli container, motor-oil bottle or milk carton in the US is 32 fl oz; a 64 fl oz juice bottle is a half gallon (2 qt).
