About US pints per hour
The US pint per hour (pt/h) equals 3.785411784×10⁻³/8/3600 ≈ 1.314×10⁻⁷ m³/s, used in US medical-device standards for slow-drip infusion and in American homebrew calculations for sparge water addition rates. A slow gravity sparge at 24 pt/h = 3 US gal/h is typical for small-batch homebrewing. 1 US pt/h ≈ 1.314×10⁻⁷ m³/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.
