mL to cc Converter — Millilitres to Cubic Centimetres
Convert millilitres (mL) to cubic centimetres (cc or cm³) and other common volume units. By the SI definition of the litre, 1 mL = 1 cc exactly — the numeric value never changes, only the label.

How does this calculator work?
1 mL equals 1 cc (cm³) exactly by the SI definition of the litre — the numeric value never changes when switching labels. To convert to other units: divide mL by 1 000 for litres, by 16.387 for cubic inches, by 29.574 for US fluid ounces. Enter any mL value to see all conversions instantly.
Formula
How this is calculated
The litre is defined in the International System of Units (SI) as exactly one cubic decimetre (dm³). A decimetre is 10 centimetres, so 1 dm³ = (10 cm)³ = 1 000 cm³. Dividing by 1 000 gives 1 mL = 1 cm³ = 1 cc. This is not an approximation — it is exact by definition, established when the litre was redefined in 1964.
The abbreviation "cc" (cubic centimetre) predates the widespread adoption of the litre and remains standard in engineering, medicine and motorsport. Engine displacements quoted in "cc" (e.g. a 998 cc motorcycle engine) contain that many millilitres of cylinder volume. Medical syringes were traditionally graduated in cc rather than mL; today the two notations are equally valid on pharmaceutical packaging.
This calculator converts any mL input to cc and simultaneously expresses the volume in litres, decilitres, cubic metres, cubic inches (1 in³ = 16.387 064 mL exactly), and US and UK fluid ounces, teaspoons and tablespoons, so you can cross-reference across the full range of common volume units.
Frequently asked questions
Yes, exactly and by definition. One millilitre equals one cubic centimetre (1 mL = 1 cm³ = 1 cc). The numeric value of any volume is identical in mL and cc; only the label differs. No calculation is needed to convert between them.
The abbreviation cc is older and predates the universal adoption of SI prefixes. It persists in medicine (syringe dosing), motorsport (engine displacement), and engineering contexts where the physical cubic-centimetre unit is conceptually clearer. Both labels are scientifically correct and interchangeable.
1 litre = 1 000 cc = 1 000 mL. This follows from 1 L = 1 dm³ = (10 cm)³ = 1 000 cm³. A 2.0-litre engine has 2 000 cc of displacement; a 500 mL water bottle holds 500 cc.
