Cubic Meter per Hour to Cubic Meter per Second (m³/h to m³/s)
Convert m³/h to m³/s — Flow Rate converter
Also written as m3/h to m3/s.
One cubic meter per hour equals 0.0002777778 m³/s, so to convert cubic meters per hour to cubic meters per second you multiply the value by 0.0002777778. A cubic meter per hour is smaller than a cubic meter per second — going the other way, 1 m³/s = 3600 m³/h. For example, 10 m³/h = 0.0027777778 m³/s and 50 m³/h = 0.01388889 m³/s.
1 m³/h = 0.0002777778 m³/s
Cubic Meter per Hour to Cubic Meter per Second formula
1 Cubic Meter per Hour = 0.0002777778 m³/s
Worked examples
- 25 m³/h = 0.0069444444 m³/s
- 100 m³/h = 0.02777778 m³/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 = 0.0002777778 m³/s.
