About Gallon per hour (GPH)
A US flow-rate unit for slow/metered flows. Used on aquarium pumps, water-feature recirculators, irrigation drip emitters, oil burners, fuel-dispensing meters, and some industrial dosing equipment. Boat fuel-flow meters also report fuel consumption in GPH, a useful figure for cruising range calculations.
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.
