Convert Liters to Cubic millimetres
1 liter is 1,000,000 mm³. One liter is exactly 1000000 cubic millimetres.
One liter is 1000000 cubic millimetres. To convert liters to cubic millimetres, multiply by 1000000; to go the other way, divide by 1000000 or multiply by 1.0000 × 10^-6. The factor is exact rather than rounded: it follows from NIST Handbook 130. One cubic decimeter.

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.
The same converter answers this pair however it is written: litres to cubic millimetres is the British spelling of the same units — the metre and the litre are spelled that way outside the United States and the quantity does not change.
How do you convert liters to cubic millimetres? The converter and the working
- 1.Take the measurement in liters.
- 2.Multiply by 1000000 — that is how many cubic millimetres fit in one liter.
- 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.
Worked example: 25 liters to cubic millimetres
- Formula
- L × 1000000 = mm³
- Arithmetic
- 25 × 1000000 = 25,000,000 mm³
- Answer
- 25 L = 25,000,000 mm³
The factor is exact, so this figure is exact too — only the display is rounded.

What is a liter?
One cubic decimeter. A liter of water weighs almost exactly one kilogram, which is how the unit was designed.
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.
How many cubic millimetres are in a liter?
One liter is 1000000 cubic millimetres, exactly. Going the other way, one cubic millimetre is 1.0000 × 10^-6 liters. 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.

The whole group — 20 units with their symbols and the size of each one in liters — is on the conversion index, along with every pair it makes. The table above already gives each of them relative to a liter.
