Measurement system: Imperial → US/Imperial length-derived

Convert Imperial fluid ounce (imp fl oz) → cubic inch (in³)

1 imp fl oz equals 1.73387145495 in³. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

Imperial fluid ounce 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 imp fl oz = 1.73387145495 in³ · 10 imp fl oz = 17.3387145495 in³.

1.73387145495 in³
