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 Litres per day
The litre per day (L/d) equals 10⁻³/86400 ≈ 1.157×10⁻⁸ m³/s, standard in water-resource management, reverse-osmosis membrane rating, and daily per-capita water-use statistics. A residential reverse-osmosis unit produces 100-300 L/d of purified water; the WHO minimum for basic household use is 50 L/d per person. 1 L/d ≈ 1.157×10⁻⁸ m³/s.
