About Gallon per hour (GPH)
A US flow-rate unit (US gallons per hour) used for slow, metered, or steady-state low-flow applications. Common applications: aquarium and pond circulation pumps (a typical canister filter for a 75-gallon aquarium delivers 250-350 GPH), water-feature and fountain recirculators, agricultural drip-irrigation emitters (rated 0.5-4 GPH at design pressure per ASABE EP458), residential oil-burner fuel nozzle ratings (most US oil furnaces use 0.5-2.0 GPH nozzles), commercial fuel-dispensing meters (where GPH is the throughput rating, often combined with a separate gallons-pumped-per-minute peak), and reverse-osmosis water-purification membranes (GPH membrane capacity is the marketing spec on most US residential RO systems). Marine fuel-flow meters typically report consumption in GPH, a useful figure for cruising range and fuel-burn-per-mile calculations. 1 GPH = 0.01667 GPM = 0.0631 L/min = 1.0515 × 10⁻⁶ m³/s.
About Liter per minute (L/min)
A metric flow-rate unit equal to 1/60,000 m³/s. L/min is the most commonly-stated metric flow unit in everyday consumer and medical contexts: household appliances and showerheads (a low-flow showerhead is 8-12 L/min vs. the older 20+ L/min designs per the EU EcoLabel showerhead criteria), garden hoses (10-30 L/min depending on supply pressure and hose diameter), medical equipment per ISO 13485 (IV-infusion pumps at fractional L/min, mechanical-ventilator tidal-volume reporting derived from L/min minute volume), oxygen-therapy nasal cannula (1-5 L/min low-flow, up to 60 L/min on high-flow nasal cannula HFNC therapy per Fisher & Paykel Airvo standards), beer-line and beverage-dispense flow controllers, dental-suction equipment, and small-flow industrial dosing pumps for chemical injection. The American Society of Anesthesiologists and the WHO oxygen-supply guidelines both quote oxygen delivery in L/min. 1 L/min = 0.2642 US GPM = 0.06 m³/hr = 16.667 mL/s.

Understanding Gallons per hour
The Gallon per hour (symbol: GPH) is a unit of volumetric flow rate. A US flow-rate unit (US gallons per hour) used for slow, metered, or steady-state low-flow applications. Common applications: aquarium and pond circulation pumps (a typical canister filter for a 75-gallon aquarium delivers 250-350 GPH), water-feature and fountain recirculators, agricultural drip-irrigation emitters (rated 0.5-4 GPH at design pressure per ASABE EP458), residential oil-burner fuel nozzle ratings (most US oil furnaces use 0.5-2.0 GPH nozzles), commercial fuel-dispensing meters (where GPH is the throughput rating, often combined with a separate gallons-pumped-per-minute peak), and reverse-osmosis water-purification membranes (GPH membrane capacity is the marketing spec on most US residential RO systems).

It belongs to the imperial measurement system.
Gallons per hour are commonly used in plumbing, HVAC systems, and chemical process engineering.
Understanding Liters per minute
The Liter per minute (symbol: L/min) is a unit of volumetric flow rate. A metric flow-rate unit equal to 1/60,000 m³/s. L/min is the most commonly-stated metric flow unit in everyday consumer and medical contexts: household appliances and showerheads (a low-flow showerhead is 8-12 L/min vs. the older 20+ L/min designs per the EU EcoLabel showerhead criteria), garden hoses (10-30 L/min depending on supply pressure and hose diameter), medical equipment per ISO 13485 (IV-infusion pumps at fractional L/min, mechanical-ventilator tidal-volume reporting derived from L/min minute volume), oxygen-therapy nasal cannula (1-5 L/min low-flow, up to 60 L/min on high-flow nasal cannula HFNC therapy per Fisher & Paykel Airvo standards), beer-line and beverage-dispense flow controllers, dental-suction equipment, and small-flow industrial dosing pumps for chemical injection.
