Measurement system: US customary → Imperial

Convert US liquid gallon (US gal) → Imperial quart (imp qt)

1 US gal equals 3.33069673852 imp qt. The name of a customary unit matters: US liquid and Imperial units are not interchangeable.

Why the distinction matters

US liquid gallon 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 gal = 3.33069673852 imp qt · 10 US gal = 33.3069673852 imp qt.
