Convert Milliliters to Cubic millimetres

1 milliliter is 1,000 mm³. One milliliter is exactly 1000 cubic millimetres.

One milliliter is 1000 cubic millimetres. To convert milliliters 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. One thousandth of a liter, and exactly one cubic centimeter.

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: millilitres 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 milliliters to cubic millimetres? The converter and the working

  1. 1.Take the measurement in milliliters.
  2. 2.Multiply by 1000 — that is how many cubic millimetres fit in one milliliter.
  3. 3.To go back the other way, divide by 1000, or multiply by 0.001.

Worked example: 25 milliliters to cubic millimetres

Formula
ml × 1000 = mm³
Arithmetic
25 × 1000 = 25,000 mm³
Answer
25 ml = 25,000 mm³

The factor is exact, so this figure is exact too — only the display is rounded.

What is a milliliter?

One thousandth of a liter, and exactly one cubic centimeter.

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 milliliter?

One milliliter is 1000 cubic millimetres, exactly. Going the other way, one cubic millimetre is 0.001 milliliters. 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.

Every volume unit here

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 milliliter.

Questions people actually ask

How many cubic millimetres are in a milliliter?
1000. 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 do I convert cubic millimetres back to milliliters?
Divide by 1000, or multiply by 0.001 — they are the same operation.
