Liter per Hour to Cubic Foot per Second (LPH to CFS)
Convert LPH to CFS — Flow Rate converter
One liter per hour equals 0.0000098096 CFS, so to convert liters per hour to cubic feet per second you multiply the value by 0.0000098096. A liter per hour is smaller than a cubic foot per second — going the other way, 1 CFS = 101940.65 LPH. For example, 10 LPH = 0.0000980963 CFS and 50 LPH = 0.0004904815 CFS.
1 LPH = 0.0000098096 CFS

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 LPH = 0.0000098096 CFS.
