Gallon (UK) per Minute to Cubic Meter per Hour (imp gal/min to m³/h)
Convert imp gal/min to m³/h — Flow Rate converter
Also written as imp gal/min to m3/h.
One gallon (UK) per minute equals 0.27276548 m³/h, so to convert gallons (UK) per minute to cubic meters per hour you multiply the value by 0.27276548. A gallon (UK) per minute is smaller than a cubic meter per hour — going the other way, 1 m³/h = 3.666153 imp gal/min. For example, 10 imp gal/min = 2.727655 m³/h and 50 imp gal/min = 13.638274 m³/h.
1 imp gal/min = 0.27276548 m³/h
Gallon (UK) per Minute to Cubic Meter per Hour formula
1 Gallon (UK) per Minute = 0.27276548 m³/h
Worked examples
- 25 imp gal/min = 6.819137 m³/h
- 100 imp gal/min = 27.276548 m³/h

Which gallon, and which trade
The single most expensive mistake in flow conversion is the gallon. A US liquid gallon is 3.785411784 litres; an imperial gallon is 4.54609 litres. US GPM and imperial GPM differ by about 20%, and pump datasheets frequently do not say which one they mean. Check the manufacturer's country of origin before trusting a GPM figure.
Different trades default to different units for the same physical quantity: HVAC and compressed air work in CFM, plumbing and pumps in GPM or LPM, and process and water engineering in m³/h or L/s. A specification that mixes them is usually quoting different equipment, not different flows. On this page, 1 imp gal/min = 0.27276548 m³/h.
