Liter per Hour to Cubic Meter per Hour (LPH to m³/h)
Convert LPH to m³/h — Flow Rate converter
Also written as LPH to m3/h.
One liter per hour equals 0.001 m³/h, so to convert liters per hour to cubic meters per hour you multiply the value by 0.001. A liter per hour is smaller than a cubic meter per hour — going the other way, 1 m³/h = 1000 LPH. For example, 10 LPH = 0.01 m³/h and 50 LPH = 0.05 m³/h.
1 LPH = 0.001 m³/h
Liter per Hour to Cubic Meter per Hour formula
1 Liter per Hour = 0.001 m³/h
Worked examples
- 25 LPH = 0.025 m³/h
- 100 LPH = 0.1 m³/h

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 LPH = 0.001 m³/h.
