Convert Cubic centimetres to Cubic millimetres
1 cubic centimetre is 1,000 mm³. One cubic centimetre is exactly 1000 cubic millimetres.
One cubic centimetre is 1000 cubic millimetres. To convert cubic centimetres to cubic millimetres, multiply by 1000; to go the other way, divide by 1000 or multiply by 0.001. The factor is exact rather than rounded: it follows from NIST Handbook 130. A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names.

How do you convert cubic centimetres to cubic millimetres? The converter and the working
- 1.Take the measurement in cubic centimetres.
- 2.Multiply by 1000 — that is how many cubic millimetres fit in one cubic centimetre.
- 3.To go back the other way, divide by 1000, or multiply by 0.001.
Worked example: 25 cubic centimetres to cubic millimetres
- Formula
- cm³ × 1000 = mm³
- Arithmetic
- 25 × 1000 = 25,000 mm³
- Answer
- 25 cm³ = 25,000 mm³
The factor is exact, so this figure is exact too — only the display is rounded.

What is a cubic centimetre?
A thousandth of a litre, which makes it exactly a millilitre — the same volume under two names. Engine displacement uses cc and medicine uses ml for the identical quantity.
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 cubic centimetre?
One cubic centimetre is 1000 cubic millimetres, exactly. Going the other way, one cubic millimetre is 0.001 cubic centimetres. 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 cubic centimetre.
