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 day
The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
