About this conversion
This page converts imperial quarts per second (imp qt/s) into us gallons per minute (gal/min), two units of volumetric flow rate.
The Imperial Quart (imp qt) is a unit of volume. The Second (s) is a unit of time.
The US Gallon (gal) is a unit of volume. The Minute (min) is a unit of time.
The formula is gal/min = imp qt/s × 18.0142, based on the fixed relationship between these two flow rate units.
Flow rate is calculated as a volume unit divided by a time unit, so every combination of a volume unit and a time unit forms a valid, exact flow rate unit.
