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 barrels per hour
The US barrel per hour (bbl/h) equals 0.158987294928/3600 ≈ 4.416×10⁻⁵ m³/s, standard in petroleum-refinery process engineering for crude-oil unit feed rates and product run-downs. Crude-distillation unit (CDU) feed is sized in bbl/h; a 100 000 bbl/d refinery processes ≈4 167 bbl/h. Process simulation software (Aspen HYSYS) uses bbl/h by default for petroleum streams. 1 bbl/h ≈ 4.416×10⁻⁵ m³/s.
