Cubic Foot per Second to Cubic Meter per Hour (CFS to m³/h)
Convert CFS to m³/h — Flow Rate converter
Also written as CFS to m3/h.
One cubic foot per second equals 101.940648 m³/h, so to convert cubic feet per second to cubic meters per hour you multiply the value by 101.940648. A cubic foot per second is larger than a cubic meter per hour — going the other way, 1 m³/h = 0.0098096296 CFS. For example, 10 CFS = 1019.41 m³/h and 50 CFS = 5097.03 m³/h.
1 CFS = 101.940648 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 CFS = 101.940648 m³/h.
