About Cubic foot per second (ft³/s)
An imperial flow-rate unit used in US hydrology, river discharge measurement, and large-scale water-supply engineering. Also called "cusec" in water-resources jargon. Typical US river flow-rate reports (USGS streamgages) use cfs. A rainstorm runoff event in a small watershed might reach 100–500 cfs. 1 ft³/s = 7.48 gallons/second ≈ 28.3 L/s.
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.
