Quarts to Liters
Convert quarts (qt) to liters (L). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
liters = quarts × 0.946352946
quarts = liters × 1.05668820943
`
One quart is 0.946353 liters, and one liter is 1.0567 quarts.

What Each Unit Is
Quarts (qt) — a quarter of a US gallon, or 0.946352946 litres. From the Latin quartus, a fourth part of a gallon.
Liters (L) — exactly one cubic decimetre, or 0.001 cubic metres. A metric volume defined for trade; briefly redefined against the kilogram before reverting in 1964.
A Sense of Scale
A US quart is just under a litre- Ice cream is sold by the quart
- A quart is two pints
- A large drink bottle is 2 L
- A car fuel tank is 45–60 L
- A bath holds about 80 L
Doing It in Your Head
Multiply by 17, then divide by 18. That is off by 0.20% — close enough to judge a
distance, a weight or a price, and not close enough to sign off on a drawing.

Precision
The factor 0.946352946 is rounded. For engineering work carry more digits than the table above, and round only at the end — rounding at each step compounds.

How Many Decimals Do You Need?
Rounding the factor costs accuracy, and how much depends on the factor. Converting 137 qt with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 qt becomes | Error |
|---|---|---|---|
| 0 | 1 | 137 | 5.6688% |
| 1 | 0.9 | 123.3 | 4.8981% |
| 2 | 0.95 | 130.15 | 0.3854% |
| 3 | 0.946 | 129.602 | 0.0373% |
| 4 | 0.9464 | 129.657 | 0.0050% |
The right number of significant figures is set by your input, not by the converter. If you measured quarts to three significant figures, the answer in liters is only good to three — writing more digits claims precision the measurement never had.
