Liter per Hour to Gallon (UK) per Minute (LPH to imp gal/min)
Convert LPH to imp gal/min — Flow Rate converter
One liter per hour equals 0.003666153 imp gal/min, so to convert liters per hour to gallons (UK) per minute you multiply the value by 0.003666153. A liter per hour is smaller than a gallon (UK) per minute — going the other way, 1 imp gal/min = 272.765484 LPH. For example, 10 LPH = 0.03666153 imp gal/min and 50 LPH = 0.18330765 imp gal/min.
1 LPH = 0.003666153 imp gal/min

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 = 0.003666153 imp gal/min.
