Measurement system: US customary → US customary

Convert US fluid ounce (US fl oz) → US liquid quart (US qt)

1 US fl oz equals 0.03125 US qt. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US fluid ounce and US liquid quart 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 = 0.03125 US qt · 10 US fl oz = 0.3125 US qt.
