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

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

1 in³ equals 0.554112554113 US fl oz. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

cubic inch and US fluid ounce 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 = 0.554112554113 US fl oz · 10 in³ = 5.54112554113 US fl oz.
