Conversion Formula
km³/yr = fl oz/h × 2.592415601e-10
About US fluid ounces per hour
The US fluid ounce per hour (fl oz/h) equals 3.785411784×10⁻³/128/3600 ≈ 8.215×10⁻⁹ m³/s, used in low-flow medical devices and slow-infusion clinical equipment. A nasal cannula oxygen humidifier delivers humidity at 10-50 fl oz/h of water vapour equivalent; micro-dosing chemical feed pumps for water treatment are calibrated in fl oz/h in US systems. 1 fl oz/h ≈ 8.215×10⁻⁹ m³/s.
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.
