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 Megalitres per day
The megalitre per day (ML/d) equals 1000/86400 ≈ 0.011574 m³/s, numerically identical to million litres per day. It is the preferred notation in Australian water-authority reporting, environmental flow assessments, and reservoir storage accounting. Murray-Darling Basin environmental flows are specified in ML/d; urban water utilities publish reservoir capacity and daily draw in ML/d. 1 ML/d ≈ 0.011574 m³/s = 1 000 m³/d.
