Convert Cubic Inches to Cubic Meters

Formula

m³ = in³ × 0.000016387064

or m³ = in³ ÷ 61023.74409473

Derivation from SI units:

• 1 in³ = (0.0254 m)³ = 1.6387064 × 10⁻⁵ m³ = 16.387064 cm³
• 1 m³ = 1 m × 1 m × 1 m

Both units are defined exactly, so the factor is exact. Cubic Inch definition: cubic inch; Cubic Meter definition: cubic meter.

Worked examples

1. A reading of 61.024 in³ converts to 0.001000004194 m³.
   61.024 in³ × 0.000016387064 = 0.001000004194 m³
2. A value of 350 in³ is 0.0057354724 m³.
   350 in³ × 0.000016387064 = 0.0057354724 m³

Where it's used

Cubic Inches are used for US engine displacement (e.g. 350 cubic inches ≈ 5.7 L), while cubic meters appear in water and gas metering. Both measure volume (capacity), so the conversion is a fixed factor.
