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

What Each Unit Is
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.
Quarts (qt) — a quarter of a US gallon, or 0.946352946 litres. From the Latin quartus, a fourth part of a gallon.
A Sense of Scale
A large drink bottle is 2 L- A car fuel tank is 45–60 L
- A bath holds about 80 L
- A US quart is just under a litre
- Ice cream is sold by the quart
- A quart is two pints
Doing It in Your Head
Multiply by 18, then divide by 17. 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 1.05668820943 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 L with the factor truncated at each decimal place:
| Decimals kept | Factor | 137 L becomes | Error |
|---|---|---|---|
| 0 | 1 | 137 | 5.3647% |
| 1 | 1.1 | 150.7 | 4.0988% |
| 2 | 1.06 | 145.22 | 0.3134% |
| 3 | 1.057 | 144.809 | 0.0295% |
| 4 | 1.0567 | 144.768 | 0.0011% |
The right number of significant figures is set by your input, not by the converter. If you measured liters to three significant figures, the answer in quarts is only good to three — writing more digits claims precision the measurement never had.
