Liter per Minute to Liter per Hour (LPM to LPH)
Convert LPM to LPH — Flow Rate converter
One liter per minute equals 60 LPH, so to convert liters per minute to liters per hour you multiply the value by 60. A liter per minute is larger than a liter per hour — going the other way, 1 LPH = 0.01666667 LPM. For example, 10 LPM = 600 LPH and 50 LPM = 3000 LPH.
1 LPM = 60 LPH
Liter per Minute to Liter per Hour formula
1 Liter per Minute = 60 LPH
Worked examples
- 25 LPM = 1500 LPH
- 100 LPM = 6000 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 LPM = 60 LPH.
