Liter per Minute to Cubic Meter per Second (LPM to m³/s)
Convert LPM to m³/s — Flow Rate converter
Also written as LPM to m3/s.
One liter per minute equals 0.0000166667 m³/s, so to convert liters per minute to cubic meters per second you multiply the value by 0.0000166667. A liter per minute is smaller than a cubic meter per second — going the other way, 1 m³/s = 60000 LPM. For example, 10 LPM = 0.0001666667 m³/s and 50 LPM = 0.0008333333 m³/s.
1 LPM = 0.0000166667 m³/s
Liter per Minute to Cubic Meter per Second formula
1 Liter per Minute = 0.0000166667 m³/s
Worked examples
- 25 LPM = 0.0004166667 m³/s
- 100 LPM = 0.0016666667 m³/s

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 = 0.0000166667 m³/s.
