Convert Cubic feet per minute to Cubic metres per hour
Convert Cubic feet per minute (ft³/min) to Cubic metres per hour (m³/h) instantly and accurately.
Conversion Formula
m³/h = ft³/min × 1.699010796
About Cubic feet per minute
The cubic foot per minute (cfm or ft³/min) equals 0.028316846592/60 ≈ 4.719×10⁻⁴ m³/s, the dominant unit for ventilation, HVAC airflow, and compressed-air system design in the US. ASHRAE ventilation standards, building-code fresh-air requirements, and dust-collector capacity are all stated in cfm. A residential HVAC system moves 800-1 200 cfm; an industrial dust collector handles 2 000-20 000 cfm. 1 cfm ≈ 0.4719 L/s.
About Cubic metres per hour
The cubic metre per hour (m³/h) equals 1/3600 m³/s ≈ 2.778×10⁻⁴ m³/s, the dominant volumetric flow unit in European process engineering, HVAC, and water treatment. Pump datasheet curves, heat-exchanger sizing software, and wastewater-treatment design all use m³/h as the standard. A domestic water pump runs at 3-8 m³/h; a municipal WWTP inlet pump handles 500-5 000 m³/h. 1 m³/h ≈ 2.778×10⁻⁴ m³/s = 1 000 L/h.
