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.
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.
