How to Convert Cubic Foot to Cubic Meter
- 1 ft³ = 0.02831684659 m³
- 1 m³ = 35.31466672 ft³
- Example: convert 15 ft³ to m³: 15 ft³ = 15 × 0.02831684659 m³ = 0.4247526989 m³
Formula
m³ = ft³ × 0.028316846592
or m³ = ft³ ÷ 35.31466672149
Derivation from SI units:
- 1 ft³ = (0.3048 m)³ = 0.028316846592 m³
- 1 m³ = 1 m × 1 m × 1 m
Both units are defined exactly, so the factor is exact. Cubic Foot definition: cubic foot; Cubic Meter definition: cubic meter.
Worked examples
- A natural-gas use of 1000 ft³ (1 Mcf) is 28.31684659 m³.
1000 ft³ × 0.02831684659 = 28.31684659 m³ - One cubic yard, 27 ft³, is 0.764554858 m³.
27 ft³ × 0.02831684659 = 0.764554858 m³
