Measurement system: US/Imperial length-derived → Imperial

Convert cubic foot (ft³) → Imperial gallon (imp gal)

1 ft³ equals 6.22883545904 imp gal. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

cubic foot and Imperial gallon belong to measurement conventions that may look familiar but are not always equivalent across countries. Mendeleev.com therefore keeps the system name next to the abbreviation and calculates from defined conversion factors rather than rounded kitchen rules.

Example

1 ft³ = 6.22883545904 imp gal · 10 ft³ = 62.2883545904 imp gal.
