How to Convert Cubic Foot to Liter
- 1 ft³ = 28.31684659 L
- 1 L = 0.03531466672 ft³
- Example: convert 15 ft³ to L: 15 ft³ = 15 × 28.31684659 L = 424.7526989 L
Formula
L = ft³ × 28.316846592
Derivation from SI units:
- 1 ft³ = (0.3048 m)³ = 0.028316846592 m³
- 1 L = 1 dm³ = (0.1 m)³ = 10⁻³ m³
- 1 ft³ = 0.028316846592 m³ ÷ 0.001 m³ per L = 28.316846592 L
Both units are defined exactly, so the factor is exact. Cubic Foot definition: cubic foot; Liter definition: liter.
Worked examples
