Measurement system: US customary → US customary

Convert US fluid ounce (US fl oz) → US cup (US cup)

1 US fl oz equals 0.125 US cup. The name of a customary unit matters: US liquid and Imperial units are not interchangeable. US fluid ounce (US fl oz) is shown explicitly so a reader can recognize the term used in recipes and measuring tools.

Why the distinction matters

US fluid ounce and US cup 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 = 0.125 US cup · 10 US fl oz = 1.25 US cup.

0.125 US cup
