Cubic Foot per Second to Liter per Hour (CFS to LPH)
Convert CFS to LPH — Flow Rate converter
One cubic foot per second equals 101940.65 LPH, so to convert cubic feet per second to liters per hour you multiply the value by 101940.65. A cubic foot per second is larger than a liter per hour — going the other way, 1 LPH = 0.0000098096 CFS. For example, 10 CFS = 1019406.48 LPH and 50 CFS = 5097032.39 LPH.
1 CFS = 101940.65 LPH

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 = 101940.65 LPH.
