Convert Cubic centimetres to Cubic inches
1 cubic centimetre is 0.06 in³. One cubic centimetre is exactly 0.0610237440947 cubic inches.
One cubic centimetre is 0.061023744 cubic inches. To convert cubic centimetres to cubic inches, multiply by 0.061023744; to go the other way, divide by 0.061023744 or multiply by 16.387064. The relation is exact but the figure is not: it is a rounding of a number that does not terminate, and 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 inches? The converter and the working
- 1.Take the measurement in cubic centimetres.
- 2.Multiply by 0.061023744 — that is how many cubic inches fit in one cubic centimetre.
- 3.To go back the other way, divide by 0.061023744, or multiply by 16.387064.
Worked example: 25 cubic centimetres to cubic inches
- Formula
- cm³ × 0.061023744 = in³
- Arithmetic
- 25 × 0.061023744 = 1.53 in³
- Answer
- 25 cm³ = 1.53 in³
The factor is rounded for display; the figure above is computed from the full value.

A cubic centimeter is a milliliter, and engine badges are rounded
One cubic inch is exactly 16.387064 cm³, and a cubic centimeter is exactly a milliliter — cc and ml are the same unit under two names. Engine displacement is where this shows up, and the badge is almost always rounded: a Chevrolet 350 is 349.85 cubic inches or 5,733 cc, sold as a 5.7 liter. Converting the badge gives the marketing number, not the engine.
NIST Handbook 44, Appendix C — general tables of units of measurement
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 inch?
Exactly 16.387064 millilitres, since the inch is exactly 25.4 mm. American engine displacement was quoted in it until the 1980s — a 350 small block is 5.7 litres.
How many cubic inches are in a cubic centimetre?
One cubic centimetre is 0.061023744 cubic inches. Going the other way, one cubic inch is 16.387064 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.
