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 minute
The litre per minute (L/min) equals 10⁻³/60 ≈ 1.667×10⁻⁵ m³/s, one of the most common flow units in consumer and light-industrial applications. Household washing machines use 10-15 L/min; oxygen concentrators deliver 1-10 L/min to patients; a standard garden sprinkler head discharges 15-30 L/min. 1 L/min ≈ 1.667×10⁻⁵ m³/s ≈ 0.2642 US gal/min.
