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.
About Cubic meter per hour (m³/hr)
A metric flow-rate unit equal to 1/3,600 m³/s. m³/hr is the standard unit for industrial process flows, HVAC air handling, pump sizing in European specifications, natural-gas metering, and municipal water treatment capacity. European building-code air-exchange requirements and pump curves are almost always expressed in m³/hr.
