About the US quarts to liters converter
To convert US quarts to liters, multiply by 0.946352946; to convert back, multiply by 1.0566882094. For example, 4 qt is about 3.785412 L. Displayed factors and results may be rounded.
US liquid quarts are common in liquid capacities and recipes. A liquid quart differs from a dry quart and from an imperial quart. Use this direction when the original amount is explicitly a US liquid measure, then round for the markings on your measuring container.
For US liquid measure, 1 US qt = 1/4 US gal = 0.946352946 L. These values are exact.
Both units are defined exactly. Calculations use 50 significant digits and round only for display.
How to convert quarts to liters
Multiply US quarts by 0.946352946: L = qt × 0.946352946. One quart is 0.946 L (946 mL), and 4 quarts, one US gallon, are 3.785 L. The factor is exact for the US liquid quart. An imperial quart is 1.1365225 L and a US dry quart about 1.101 L.
Why a quart is 0.946352946 L
The US liquid quart is a quarter of the US gallon, defined as 231 cubic inches. With the inch fixed at 2.54 cm, the gallon is exactly 3.785411784 L and the quart 0.946352946 L (NIST Handbook 44, Appendix C).
A quart is about 5.4% smaller than a liter. Going the other way, a liter is 1.0567 quarts.

A quart is 2 pints, 4 cups or 32 fluid ounces, so a 32 fl oz carton holds 946 mL. A 12-quart stockpot holds 11.36 L.
How many liters is 5 quarts of oil?
US owner's manuals list engine oil capacity in quarts. An engine that takes 5 quarts needs 4.73 L (4.73176473), so a 5 L jug covers it with 0.27 L to spare.
Imperial and dry quarts are different sizes
An imperial quart is a quarter of the 4.54609 L imperial gallon (official imperial tables), so it is 1.1365225 L, about 20% more than a US quart. Four imperial quarts make 4.54609 L, against 3.785411784 L for four US quarts.
A US dry quart, used for produce such as berries, is 1/32 of a bushel: 67.200625 cubic inches, or 1.101220942715 L. Check which quart a label or recipe means before converting.
Common mistakes
- Counting a quart as a liter. It works for a rough guess, but 4 quarts come out 0.214588216 L too high (4 L instead of 3.785411784 L), and 12 quarts 0.64 L too high.
- Dividing by 0.946352946. That turns 4 quarts into 4.23 L, which is the liters-to-quarts direction. The liter figure is always the smaller number.
- Writing 1 quart 1 pint as 1.1. A pint is half a quart, so the amount is 1.5 quarts (type
1+1/2), or 1.419529419 L.
