Liter per Minute to Cubic Foot per Second (LPM to CFS)
Convert LPM to CFS — Flow Rate converter
One liter per minute equals 0.0005885778 CFS, so to convert liters per minute to cubic feet per second you multiply the value by 0.0005885778. A liter per minute is smaller than a cubic foot per second — going the other way, 1 CFS = 1699.01 LPM. For example, 10 LPM = 0.0058857778 CFS and 50 LPM = 0.02942889 CFS.
1 LPM = 0.0005885778 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 LPM = 0.0005885778 CFS.
