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.
About UK pints per hour
The UK pint per hour (pt/h) equals 4.54609×10⁻³/8/3600 ≈ 1.578×10⁻⁷ m³/s, used in British slow-infusion clinical records and historical dairy milk-flow measurements before metrication. An IV drip set at 100 mL/h equals ≈176 UK fl oz/h ≈ 8.8 UK pt/h. 1 UK pt/h ≈ 1.578×10⁻⁷ m³/s.
