How to Convert Cubic Inch to Cubic Centimeter
- 1 in³ = 16.387064 cm³
- 1 cm³ = 0.06102374409 in³
- Example: convert 15 in³ to cm³: 15 in³ = 15 × 16.387064 cm³ = 245.80596 cm³
Formula
cm³ = in³ × 16.387064
Derivation from SI units:
- 1 in³ = (0.0254 m)³ = 1.6387064 × 10⁻⁵ m³ = 16.387064 cm³
- 1 cm³ = (0.01 m)³ = 10⁻⁶ m³ = 1 mL
- 1 in³ = 0.000016387064 m³ ÷ 0.000001 m³ per cm³ = 16.387064 cm³
Both units are defined exactly, so the factor is exact. Cubic Inch definition: cubic inch; Cubic Centimeter definition: cubic centimeter.
Worked examples
- A 350 in³ V8 displaces 5735.4724 cm³.
350 in³ × 16.387064 = 5735.4724 cm³ - 1 in³ is exactly 16.387064 cm³.
1 in³ × 16.387064 = 16.387064 cm³
