Cubic Meter per Second to Cubic Meter per Hour (m³/s to m³/h)
Convert m³/s to m³/h — Flow Rate converter
Also written as m3/s to m3/h.
One cubic meter per second equals 3600 m³/h, so to convert cubic meters per second to cubic meters per hour you multiply the value by 3600. A cubic meter per second is larger than a cubic meter per hour — going the other way, 1 m³/h = 0.0002777778 m³/s. For example, 10 m³/s = 36000 m³/h and 50 m³/s = 180000 m³/h.
1 m³/s = 3600 m³/h
Cubic Meter per Second to Cubic Meter per Hour formula
1 Cubic Meter per Second = 3600 m³/h
Worked examples
- 25 m³/s = 90000 m³/h
- 100 m³/s = 360000 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 m³/s = 3600 m³/h.
