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.
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.
