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 Million litres per day
The million litres per day (ML/d or MLD) equals 1000/86400 ≈ 0.011574 m³/s, the standard capacity unit for water-treatment plants, sewage-treatment works, and desalination facilities in the UK, India, and much of the Commonwealth. A small town water-treatment works processes 5-20 ML/d; the Beckton Sewage Treatment Works in London treats ≈700 ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
