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 Cubic foot per minute (CFM)
An imperial flow-rate unit dominant in US HVAC — air-handler capacity, duct sizing, bathroom/kitchen exhaust fan ratings, compressed-air-system sizing, and dust collection. A residential bathroom fan is typically 50–110 CFM; a central-AC air handler for a 2,000 ft² home delivers 800–1,200 CFM. Converting CFM to m³/hr (×1.699) is common for international HVAC equipment.
