About this conversion
This page converts cubic feet per hour (ft3/h) into imperial gallons per second (imp gal/s), two units of volumetric flow rate.
The Cubic Foot (ft3) is a unit of volume. The Hour (h) 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 = ft3/h × 0.00173023, 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.
