About Cubic foot per second (ft³/s)
An imperial flow-rate unit used predominantly in US hydrology, river-discharge measurement, water-resource engineering, and large-scale waterworks design. Also called "cfs" or the colloquial "cusec" in US water-resources jargon. The US Geological Survey (USGS) StreamStats and the National Water Information System publish all US river streamgage data in cfs — a federal reporting standard since the 1950s. US Army Corps of Engineers flood-routing analyses, FEMA flood-insurance studies, and state water-rights records (especially in the western US under prior-appropriation doctrine) all measure discharge in cfs. Reference values: a small headwater stream might flow 5-20 cfs at base flow and 200-500 cfs during a 100-year storm; the Colorado River below Glen Canyon Dam is typically 8,000-25,000 cfs; the lower Mississippi runs 350,000-600,000 cfs depending on the season. 1 ft³/s = 7.4805 US gallons per second = 449 GPM = 28.32 L/s = 0.02832 m³/s.
About Cubic foot per minute (CFM)
An imperial flow-rate unit dominant in US HVAC, dust collection, and compressed-air system engineering. CFM is the working unit for air-handler capacity (ASHRAE 62.1, AMCA 210), residential duct sizing (Manual D ACCA design), bathroom and kitchen exhaust-fan ratings (the Home Ventilation Institute Certified Performance Ratings list each fan model's HVI-tested CFM), compressed-air-system sizing (compressor manufacturer ratings under ISO 1217 are dual-quoted as SCFM and CFM displacement), and dust-collection ducting per OSHA 29 CFR 1910 and NFPA 654. Reference values: a residential bath fan is 50-110 CFM (HVI minimum 50 CFM for code), a central-AC air handler for a 2,000 ft² US home delivers 800-1,200 CFM (1 CFM per ft² is a typical Manual J residential figure), a large industrial centrifugal compressor 5,000-20,000 SCFM. Convert CFM to m³/hr by multiplying by 1.699; to L/s by multiplying by 0.4719; to m³/s by multiplying by 4.7195 × 10⁻⁴.
