Liter per Minute to Liter per Second (LPM to LPS)
Convert LPM to LPS — Flow Rate converter
One liter per minute equals 0.01666667 LPS, so to convert liters per minute to liters per second you multiply the value by 0.01666667. A liter per minute is smaller than a liter per second — going the other way, 1 LPS = 60 LPM. For example, 10 LPM = 0.16666667 LPS and 50 LPM = 0.83333333 LPS.
1 LPM = 0.01666667 LPS

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 = 0.01666667 LPS.
