Convert Cubic feet per minute to Litres per hour
Convert Cubic feet per minute (ft³/min) to Litres per hour (L/h) instantly and accurately.
Conversion Formula
L/h = ft³/min × 1699.010796
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 Litres per hour
The litre per hour (L/h) equals 10⁻³/3600 ≈ 2.778×10⁻⁷ m³/s, widely used in automotive fuel consumption (L/h), irrigation drip systems, and small pump specifications. A fuel cell vehicle running on hydrogen consumes ±2 L/h of liquid equivalent; a domestic water softener regeneration cycle uses 40-100 L/h of brine. 1 L/h ≈ 2.778×10⁻⁷ m³/s ≈ 0.2642 US gal/h.
