Measurement system: US/Imperial length-derived → Imperial

Convert cubic inch (in³) → Imperial gallon (imp gal)

1 in³ equals 0.00360465014991 imp gal. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

cubic inch 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 in³ = 0.00360465014991 imp gal · 10 in³ = 0.0360465014991 imp gal.
