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 minute (GPM)
A US customary flow-rate unit (US gallons per minute, where 1 US gallon = 3.785411784 liters per NIST SP 811) used universally in US plumbing, HVAC, fire protection, agricultural irrigation, and swimming-pool circulation. GPM is the primary US sizing unit for residential water softeners (the IAPMO Z601 test method rates ion-exchange capacity at a defined GPM), well-pump submersibles, lawn sprinkler design (the GPM at each emitter sets zone sizing), NFPA 13 fire-sprinkler systems (head-flow allocations in GPM), and pool circulation (turnover rates require X GPM × hours). Reference values: a US WaterSense-certified showerhead is ≤ 2.0 GPM, an older US showerhead is 2.5-3 GPM, a residential dishwasher is ~3-4 GPM peak, a 4-inch municipal fire hydrant delivers 500-1,500 GPM (NFPA test pressure 20 psi residual). 1 GPM = 3.7854 L/min = 0.06309 L/s. Care: US GPM ≠ Imperial GPM (a UK gallon is 4.54609 L, so 1 Imperial GPM = 1.201 US GPM).

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. 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.
