What is a Cubic Foot?

Cubic Foot is a volume unit used for liquids, containers, storage and technical capacity calculations.

Cubic Foot is a volume unit used for liquids, containers, storage and technical capacity calculations.

The cubic foot follows from the international foot of exactly 0.3048 m (1959), so 1 ft³ is about 28.317 liters.

Measurement system: Metric, imperial and practical fluid-capacity usage. SI equivalent: 1 ft³ = 0.028316846592 m³.
