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 Liter per minute (L/min)
A metric flow-rate unit equal to 1/60,000 m³/s. L/min is the most commonly-stated metric flow unit in everyday consumer and medical contexts: household appliances and showerheads (a low-flow showerhead is 8-12 L/min vs. the older 20+ L/min designs per the EU EcoLabel showerhead criteria), garden hoses (10-30 L/min depending on supply pressure and hose diameter), medical equipment per ISO 13485 (IV-infusion pumps at fractional L/min, mechanical-ventilator tidal-volume reporting derived from L/min minute volume), oxygen-therapy nasal cannula (1-5 L/min low-flow, up to 60 L/min on high-flow nasal cannula HFNC therapy per Fisher & Paykel Airvo standards), beer-line and beverage-dispense flow controllers, dental-suction equipment, and small-flow industrial dosing pumps for chemical injection. The American Society of Anesthesiologists and the WHO oxygen-supply guidelines both quote oxygen delivery in L/min. 1 L/min = 0.2642 US GPM = 0.06 m³/hr = 16.667 mL/s.
