Measurement system: US customary → SI

Convert US liquid quart (US qt) → millilitre (mL)

1 US qt equals 946.352946 mL. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US liquid quart and millilitre 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 = 946.352946 mL · 10 US qt = 9 463.52946 mL.
