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 US pints per minute
The US pint per minute (pt/min) equals 3.785411784×10⁻³/8/60 ≈ 7.886×10⁻⁶ m³/s, a unit encountered in US home-brewing, small-batch winery transfers, and consumer-grade pump ratings. A standard kitchen faucet running at 2 US gal/min produces 16 pt/min; a small submersible pond pump rated 50 gal/h delivers ≈27 pt/min. 1 US pt/min ≈ 7.886×10⁻⁶ m³/s.
