Liters to US Quarts Converter (L to qt)
1 L ≈ 1.056688 US quarts. Convert liters to US quarts for engine oil capacities, metric cookware and recipes, with liter and quart charts.
US Quart (qt) = Liter (L) × 1.05668820943
Liter (L): The liter is the metric unit of volume accepted for use with the SI. Since 1964 it has been defined as exactly one cubic decimeter, which is 1,000 cubic centimeters.
US Quart (qt): A US liquid quart is a quarter of a US gallon: 2 US pints, 32 US fluid ounces or exactly 0.946352946 liters. It is a common size for milk, oil and stock.
| Liter (L) | US Quart (qt) |
|---|---|
| 1 | 1.05668820943 |
| 5 | 5.28344104716 |
| 10 | 10.5668820943 |
| 25 | 26.4172052358 |

Engine oil and coolant capacities are often specified in liters, while US auto parts stores sell oil by the quart. One liter is about 1.06 US quarts, so an engine that takes 4.7 L needs almost exactly 5 quarts; the first chart lists capacities in small steps between 3.5 and 6.5 L, where most car engines fall. Coolant is usually sold in US gallon jugs instead, and a cooling system listed at 7.5 L takes about 2 gallons of mixed coolant.
Metric cookware works the same way: a 6 L pressure cooker or a 2 L saucepan is easier to match to a US recipe once it is in quarts. The quart here is the US liquid quart of 0.946352946 L; for a British quart, multiply liters by about 0.88 instead.

Quick mental estimate
Add 6% to the liters: 4 L → 4 + 0.24 = 4.24 qt. The exact figure is 4.227 qt, so the shortcut is about 0.3% high.
Use the converter or the charts when the exact figure matters.
The two units
Liter (L): The liter is the metric unit of volume accepted for use with the SI. Since 1964 it has been defined as exactly one cubic decimeter, which is 1,000 cubic centimeters.

Frequently asked questions
How many quarts is 5 liters of oil?
About 5.28 US quarts, so five quart bottles leave the engine a little short. Pour in five, check the dipstick, then add from a sixth bottle as needed.
Is a liter more than a quart?
Yes, by about 5.7% for the US liquid quart: 1 L is about 1.057 US qt. A British quart, at 1.137 L, is larger than a liter.
Why does my bottle say 946 mL instead of 1 quart?
US packaging rules call for the net quantity in both US and metric units, and one US quart is 946.35 mL, which rounds to 946 mL. The bottle holds a quart, not a liter.
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.
