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 Cubic meter per hour (m³/hr)
A metric flow-rate unit equal to exactly 1/3,600 m³/s. m³/hr is the de-facto standard unit for industrial process flows in metric countries, HVAC air handling (DIN EN 16798 / ASHRAE 62.1 ventilation calcs), pump sizing in European pump curves (KSB, Grundfos, Wilo specifications), natural-gas metering and the gas grid balance reports (TSO data is in Mm³/hr), municipal water-treatment plant capacity, and biogas/anaerobic-digester output. European building-code minimum air-exchange rates (e.g., German DIN 1946 fresh-air requirements per occupant) and Eurovent-certified fan-coil ratings are almost always expressed in m³/hr. Practical reference: a typical residential heat-recovery ventilation unit moves 100-400 m³/hr; an industrial centrifugal pump might be rated at 50-5,000 m³/hr. Convert to GPM by multiplying by 4.403, to CFM by multiplying by 0.5886, to L/s by dividing by 3.6.
