Measurement system: US customary → US/Imperial length-derived

Convert US liquid gallon (US gal) → cubic inch (in³)

1 US gal equals 231 in³. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US liquid gallon and cubic inch 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 US gal = 231 in³ · 10 US gal = 2 310 in³.

231 in³
