Quarts to Milliliters
Convert quarts (qt) to milliliters (mL). Both measure capacity and volume, and the conversion comes up in cooking, chemistry, fuel work.
The Formula
``
milliliters = quarts × 946.352946
quarts = milliliters × 0.00105668820943
`
One quart is 946.3529 milliliters, and one milliliter is 0.001057 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.
Milliliters (mL) — one thousandth of a litre, equal to one cubic centimetre. The metric unit for small volumes; medicine and cooking both work in millilitres.
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 teaspoon is 5 mL
- An espresso is 30 mL
- A wine glass pour is 150 mL
Precision
The factor 946.352946 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 | 946 | 129,602 | 0.0373% |
| 1 | 946.4 | 129,656.8 | 0.0050% |
| 2 | 946.35 | 129,649.95 | 0.0003% |
| 3 | 946.353 | 129,650.36 | — |
| 4 | 946.3529 | 129,650.35 | — |
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 milliliters is only good to three — writing more digits claims precision the measurement never had.
