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 second (L/s)
A metric flow-rate unit equal to 0.001 m³/s. L/s is the typical unit for plumbing fixtures in metric-using countries, fire-pump capacities, and medium-flow industrial processes. A typical kitchen faucet is 0.1–0.15 L/s; a fire hydrant can deliver 30–60 L/s. Converting L/s to GPM (×15.85) is routine for international pump and plumbing equipment.
