Cubic Meter per Hour to Liter per Second (m³/h to LPS)
Convert m³/h to LPS — Flow Rate converter
Also written as m3/h to LPS.
One cubic meter per hour equals 0.27777778 LPS, so to convert cubic meters per hour to liters per second you multiply the value by 0.27777778. A cubic meter per hour is smaller than a liter per second — going the other way, 1 LPS = 3.6 m³/h. For example, 10 m³/h = 2.777778 LPS and 50 m³/h = 13.888889 LPS.
1 m³/h = 0.27777778 LPS

1 Cubic Meter per Hour = 0.27777778 LPS
Worked examples
- 25 m³/h = 6.944444 LPS
- 100 m³/h = 27.777778 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/h = 0.27777778 LPS.
