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

Convert US fluid ounce (US fl oz) → cubic inch (in³)

1 US fl oz equals 1.8046875 in³. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US 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 US fl oz = 1.8046875 in³ · 10 US fl oz = 18.046875 in³.

1.8046875 in³
