Convert Cubic metres to Milliliters
1 cubic metre is 1,000,000 ml. One cubic metre is exactly 1000000 milliliters.
One cubic metre is 1000000 milliliters. To convert cubic metres to milliliters, 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. Exactly a thousand litres, by the definition of the litre.

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: cubic metres to millilitres 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 cubic metres to milliliters? The converter and the working
- 1.Take the measurement in cubic metres.
- 2.Multiply by 1000000 — that is how many milliliters fit in one cubic metre.
- 3.To go back the other way, divide by 1000000, or multiply by 1.0000 × 10^-6.
Worked example: 25 cubic metres to milliliters
- Formula
- m³ × 1000000 = ml
- Arithmetic
- 25 × 1000000 = 25,000,000 ml
- Answer
- 25 m³ = 25,000,000 ml
The factor is exact, so this figure is exact too — only the display is rounded.

What is a cubic metre?
Exactly a thousand litres, by the definition of the litre. The SI unit of volume, and how the rest of the world orders concrete.
What is a milliliter?
One thousandth of a liter, and exactly one cubic centimeter.
How many milliliters are in a cubic metre?
One cubic metre is 1000000 milliliters, exactly. Going the other way, one milliliter is 1.0000 × 10^-6 cubic metres. 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.
