Measurement system: US customary → US customary

Convert US liquid quart (US qt) → US cup (US cup)

1 US qt equals 4 US cup. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US liquid quart 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 qt = 4 US cup · 10 US qt = 40 US cup.

4 US cup
