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 Kilolitres per day
The kilolitre per day (kL/d) equals 1/86400 ≈ 1.157×10⁻⁵ m³/s, the standard unit for per-household and per-property water-consumption billing in Australia. Sydney Water and other Australian utilities charge tariffs per kL/d consumed; a typical Australian household uses 0.6-1.0 kL/d. 1 kL/d = 1 m³/d ≈ 264.2 US gal/d.
