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.
About Cubic kilometres per year
The cubic kilometre per year (km³/yr) equals 10⁹/(365.25×86400) ≈ 31.688 m³/s, the unit used in global hydrology, glaciology, and climate science for river basin runoff, ice-sheet mass balance, and groundwater storage change. Total global freshwater river runoff is ≈37 000 km³/yr; the Amazon alone contributes ≈6 600 km³/yr; the Greenland ice sheet loses ≈280 km³/yr to melt and calving. 1 km³/yr ≈ 31.69 m³/s.
