Cubic Meter per Second to Gallon (US) per Hour (m³/s to gal/h)
Convert m³/s to gal/h — Flow Rate converter
Also written as m3/s to gal/h.
One cubic meter per second equals 951019.39 gal/h, so to convert cubic meters per second to gallons (US) per hour you multiply the value by 951019.39. A cubic meter per second is larger than a gallon (US) per hour — going the other way, 1 gal/h = 0.0000010515 m³/s. For example, 10 m³/s = 9510193.89 gal/h and 50 m³/s = 47550969.43 gal/h.
1 m³/s = 951019.39 gal/h
Cubic Meter per Second to Gallon (US) per Hour formula

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 m³/s = 951019.39 gal/h.
