About this conversion
This page converts imperial gallons per hour (imp gal/h) into cubic meters per hour (m3/h), two units of volumetric flow rate.
The Imperial Gallon (imp gal) is a unit of volume. The Hour (h) is a unit of time.
The Cubic Meter (m3) is a unit of volume. The Hour (h) is a unit of time.
The formula is m3/h = imp gal/h × 0.00454609, 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.
