Convert Cubic millimetres to US quarts
1 cubic millimetre is 0.000001057 qt. One cubic millimetre is exactly 0.00000105668820943 US quarts.
One cubic millimetre is 1.0567 × 10^-6 US quarts. To convert cubic millimetres to US quarts, multiply by 1.0567 × 10^-6; to go the other way, divide by 1.0567 × 10^-6 or multiply by 946352.95. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and it follows from NIST Handbook 130. A millionth of a litre, because the millimetre is a thousandth of a metre and volume cubes the factor.

How do you convert cubic millimetres to US quarts? The converter and the working
- 1.Take the measurement in cubic millimetres.
- 2.Multiply by 1.0567 × 10^-6 — that is how many US quarts fit in one cubic millimetre.
- 3.To go back the other way, divide by 1.0567 × 10^-6, or multiply by 946352.95.
Worked example: 25 cubic millimetres to US quarts
- Formula
- mm³ × 1.0567 × 10^-6 = qt
- Arithmetic
- 25 × 1.0567 × 10^-6 = 0.00002642 qt
- Answer
- 25 mm³ = 0.00002642 qt
The factor is rounded for display; the figure above is computed from the full value.

What is a cubic millimetre?
A millionth of a litre, because the millimetre is a thousandth of a metre and volume cubes the factor. A microlitre by another name, and the unit injection-moulding shot sizes are quoted in.
What is a US quart?
Two pints, about 946 ml, and close enough to a liter that recipes swap them.
How many US quarts are in a cubic millimetre?
One cubic millimetre is 1.0567 × 10^-6 US quarts. Going the other way, one US quart is 946352.95 cubic millimetres. Both figures come from the same defined relation rather than from a measurement, which is why they are the same today as they were in 1959.
