About this conversion
This page converts us gallons per minute (gal/min) into imperial gallons per second (imp gal/s), two units of volumetric flow rate.
The US Gallon (gal) is a unit of volume. The Minute (min) is a unit of time.
The Imperial Gallon (imp gal) is a unit of volume. The Second (s) is a unit of time.
The formula is imp gal/s = gal/min × 0.0138779, 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.
