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

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 = 1000 LPH.
