About Liter per second (L/s)
A metric flow-rate unit equal to exactly 0.001 m³/s. L/s is the typical unit for plumbing fixtures in metric-using countries, the SI-aligned sizing unit for water-supply mains (per ISO 4064 water meter specs and EN 805 European water-supply standard), fire-pump capacities (often dual-listed in L/s and m³/hr on European fire-rated pumps), and medium-flow industrial processes. Reference values: a typical kitchen faucet flows 0.1-0.15 L/s, a metric shower head 0.13-0.20 L/s, a 50 mm domestic-water service ~3-5 L/s, a 100 mm fire-hydrant supply main 30-60 L/s. Converting L/s to GPM (US gallons per minute) is multiply by 15.85 — one of the most-needed unit conversions for buyers of imported European pump/plumbing equipment specifying performance in metric units. 1 L/s = 60 L/min = 3.6 m³/hr.
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.
