About Gallon per minute (GPM)
A US customary flow-rate unit (US gallons per minute) used in plumbing, HVAC, fire protection, and swimming-pool circulation. GPM is the primary US sizing unit for residential water softeners, well pumps, sprinkler systems, and NFPA-standard fire-protection systems. A typical US showerhead is 2–2.5 GPM; a 4-inch fire hydrant can deliver 500–1,500 GPM. 1 GPM ≈ 3.785 L/min.
About Liter per minute (L/min)
A metric flow-rate unit commonly used for household appliances, medical devices (IV pumps, ventilators), dispensing equipment, and small-flow industrial processes. A shower head in a metric country is typically 8–12 L/min; a garden hose is 10–30 L/min. L/min is the default unit for oxygen delivery in medicine (nasal cannula at 1–5 L/min).
