Cubic Meter per Hour to Gallon (US) per Second (m³/h to gal/s)
Convert m³/h to gal/s — Flow Rate converter
Also written as m3/h to gal/s.
One cubic meter per hour equals 0.07338113 gal/s, so to convert cubic meters per hour to gallons (US) per second you multiply the value by 0.07338113. A cubic meter per hour is smaller than a gallon (US) per second — going the other way, 1 gal/s = 13.627482 m³/h. For example, 10 m³/h = 0.73381126 gal/s and 50 m³/h = 3.669056 gal/s.
1 m³/h = 0.07338113 gal/s

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/h = 0.07338113 gal/s.
