Cubic Meter per Second to Liter per Second (m³/s to LPS)
Convert m³/s to LPS — Flow Rate converter
Also written as m3/s to LPS.
One cubic meter per second equals 1000 LPS, so to convert cubic meters per second to liters per second you multiply the value by 1000. A cubic meter per second is larger than a liter per second — going the other way, 1 LPS = 0.001 m³/s. For example, 10 m³/s = 10000 LPS and 50 m³/s = 50000 LPS.
1 m³/s = 1000 LPS
Cubic Meter per Second to Liter per Second formula
1 Cubic Meter per Second = 1000 LPS
Worked examples
- 25 m³/s = 25000 LPS
- 100 m³/s = 100000 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 m³/s = 1000 LPS.
