Measurement system: US customary → Imperial

Convert US cup (US cup) → Imperial quart (imp qt)

1 US cup equals 0.208168546157 imp qt. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US cup and Imperial 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 cup = 0.208168546157 imp qt · 10 US cup = 2.08168546157 imp qt.
