Convert Cubic millimetres to Cubic yards
1 cubic millimetre is 1.31e-9 yd³. One cubic millimetre is exactly 1.30795061931e-9 cubic yards.
One cubic millimetre is 1.3080 × 10^-9 cubic yards. To convert cubic millimetres to cubic yards, multiply by 1.3080 × 10^-9; to go the other way, divide by 1.3080 × 10^-9 or multiply by 7.6455 × 10^+8. 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.

Factors are entered by hand from NIST Handbook 130 rather than derived from a units library, so the ones that terminate are exact rather than rounded.
How do you convert cubic millimetres to cubic yards? The converter and the working
- 1.Take the measurement in cubic millimetres.
- 2.Multiply by 1.3080 × 10^-9 — that is how many cubic yards fit in one cubic millimetre.
- 3.To go back the other way, divide by 1.3080 × 10^-9, or multiply by 7.6455 × 10^+8.
Worked example: 25 cubic millimetres to cubic yards
- Formula
- mm³ × 1.3080 × 10^-9 = yd³
- Arithmetic
- 25 × 1.3080 × 10^-9 = 3.27e-8 yd³
- Answer
- 25 mm³ = 3.27e-8 yd³
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 cubic yard?
Twenty-seven cubic feet, or 764.55 litres. Concrete, topsoil and aggregate are all ordered by it in the US, and it is the unit a truck is measured in.
How many cubic yards are in a cubic millimetre?
One cubic millimetre is 1.3080 × 10^-9 cubic yards. Going the other way, one cubic yard is 7.6455 × 10^+8 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.
