Convert Cubic Centimeters to Cubic Feet

Formula

ft³ = cm³ × 0.00003531466672149

or ft³ = cm³ ÷ 28316.846592

Derivation from SI units:

• 1 cm³ = (0.01 m)³ = 10⁻⁶ m³ = 1 mL
• 1 ft³ = (0.3048 m)³ = 0.028316846592 m³
• 1 cm³ = 0.000001 m³ ÷ 0.028316846592 m³ per ft³ = 0.00003531466672149 ft³

Both units are defined exactly, so the factor is exact. Cubic Centimeter definition: cubic centimeter; Cubic Foot definition: cubic foot.

Worked examples

1. A reading of 10 cm³ converts to 0.0003531466672 ft³.
   10 cm³ × 0.00003531466672 = 0.0003531466672 ft³
2. A value of 500 cm³ is 0.01765733336 ft³.
   500 cm³ × 0.00003531466672 = 0.01765733336 ft³

Where it's used

Cubic Centimeters are used for engine displacement (e.g. 125 cc, 1600 cc), while cubic feet appear in natural gas billing (ccf, Mcf). Both measure volume (capacity), so the conversion is a fixed factor.
