How to Convert Cubic Inch to Liter
- 1 in³ = 0.016387064 L
- 1 L = 61.02374409 in³
- Example: convert 15 in³ to L: 15 in³ = 15 × 0.016387064 L = 0.24580596 L
Formula
L = in³ × 0.016387064
or L = in³ ÷ 61.02374409473
Derivation from SI units:
- 1 in³ = (0.0254 m)³ = 1.6387064 × 10⁻⁵ m³ = 16.387064 cm³
- 1 L = 1 dm³ = (0.1 m)³ = 10⁻³ m³
- 1 in³ = 0.000016387064 m³ ÷ 0.001 m³ per L = 0.016387064 L
Both units are defined exactly, so the factor is exact. Cubic Inch definition: cubic inch; Liter definition: liter.
Worked examples
- A 427 in³ engine displaces 6.997276328 L.
427 in³ × 0.016387064 = 6.997276328 L - 231 in³ is one US gallon, 3.785411784 L.
231 in³ × 0.016387064 = 3.785411784 L
