US Quarts to Litres converter
This free volume converter changes US liquid quarts (qt) into litres (L) and back again, in real time. It is built for cooking and baking with US recipes, checking the capacity of jugs, bottles and cookware, and any quick metric-to-US volume conversion. The US liquid quart is slightly smaller than a litre, which is why a quart converts to just under one litre.
How it works
The converter uses the exact definition 1 US liquid quart = 0.946352946 litres. To go from quarts to litres it multiplies, and to go from litres to quarts it divides:
L = qt × 0.946352946
qt = L ÷ 0.946352946Both fields are linked: whichever field you last edited is treated as the input, and the other updates instantly. Results are rounded for readability — more decimal places are shown for small numbers and fewer for large ones — and very large or very small values switch to scientific notation.
Example
Convert 2 quarts to litres: 2 × 0.946352946 = 1.8927 L.
Going the other way, 1 litre is 1 ÷ 0.946352946 = 1.0567 qt. And because a US gallon is exactly 4 quarts, 4 qt = 3.7854 L — a handy check against the gallon figure.
| US quarts (qt) | Litres (L) |
|---|---|
| 1 qt | 0.9464 L |
| 2 qt | 1.8927 L |
| 4 qt | 3.7854 L |
| 10 qt | 9.4635 L |
US quarts versus imperial quarts
The US liquid quart and the UK (imperial) quart are not the same. The US liquid quart is 0.9464 litres, while the imperial quart is larger at approximately 1.1365 litres. This distinction matters most when scaling a recipe or measuring liquid capacity, because a quart of something in a UK recipe is roughly 20% more than a quart in a US recipe.
This converter uses the US liquid quart throughout. If you are working with UK or Commonwealth measurements, you will need a separate imperial quart converter.
Common cooking and baking contexts
US recipes often list volumes in quarts for soups, stocks, and brines. Here are the quart measures most likely to appear in a recipe and their metric equivalents:
- 1 quart ≈ 0.95 L — a standard pot of chicken stock or a large batch of soup
- 2 quarts ≈ 1.89 L — close to a standard large saucepan
- 3 quarts ≈ 2.84 L — a medium Dutch oven
- 4 quarts ≈ 3.79 L — one US gallon, the typical large stockpot
When a US recipe specifies a “4-quart pot”, that corresponds to a pot with roughly a 4-litre capacity in metric kitchens.
Quarts in the US customary system
The quart sits within the US liquid volume hierarchy: 2 cups = 1 pint, 2 pints = 1 quart, 4 quarts = 1 gallon. Knowing this chain makes scaling recipes straightforward — halving a quart gives you a pint, halving again gives you a cup. In metric, a cup is approximately 237 ml, a pint approximately 473 ml, and a quart approximately 946 ml.
