In the US the quart sizes motor oil, ice cream, cookware and coolers, while owner's manuals for imported cars and recipes from abroad give the same volumes in liters. Four US quarts make a gallon, so each one is exactly 0.946352946 L, a little over 5% short of a liter.
The household table lists quart sizes printed on American products. When topping up oil in a car specified in liters, add the quart bottles first and finish by checking the dipstick, since a full quart is noticeably less than a liter. Strawberries and other produce sold by the quart use the larger dry quart, which this chart does not cover.

Frequently asked questions
Is a quart bigger than a liter?
No. A US liquid quart is 0.946 L, so a liter holds about 1.06 US quarts. The UK quart is a different, larger unit of about 1.137 L, so a British quart is bigger than a liter.
What is a dry quart?
A US dry quart is 1/32 of a US bushel, about 1.101 L, and is used for produce such as berries and cherry tomatoes. It is about 16% larger than the liquid quart, so it is the wrong figure for liquids.
How many liters are in a quart of motor oil?
A US quart bottle holds 0.946 L, usually printed as 946 mL on the label. Oil sold in Europe and Asia commonly comes in 1 L, 4 L and 5 L containers, so the number of containers for the same engine differs.
How precise is the result?
The converter uses the exact definitions above with browser floating-point arithmetic and shows up to 12 significant digits. The charts round to four decimal places for reading.
