About UK pints per minute
The UK pint per minute (pt/min) equals 4.54609×10⁻³/8/60 ≈ 9.471×10⁻⁶ m³/s, common in British beer-dispense engineering and pump datasheets pre-metrication. A cellar gas dispense system pressurising beer lines at 2 UK pt/min per tap maintains balanced flow for a 6-tap bar. 1 UK pt/min ≈ 9.471×10⁻⁶ m³/s ≈ 0.5683 L/min.

The US gallon per day (gpd) equals 3.785411784×10⁻³/86400 ≈ 4.381×10⁻⁸ m³/s, the standard unit in US water-utility regulation and residential water-well pump sizing. The US national average residential water use is about 80-100 gpd per person; a reverse-osmosis membrane module is rated in gpd (50-100 gpd for domestic units). 1 US gpd ≈ 4.381×10⁻⁸ m³/s.
