Convert Microlitres per hour to Cubic kilometres per year
Convert Microlitres per hour (µL/h) to Cubic kilometres per year (km³/yr) instantly and accurately.
Conversion Formula
km³/yr = µL/h × 8.766000000e-15
About Microlitres per hour
The microlitre per hour (µL/h) equals 10⁻⁹/3600 ≈ 2.778×10⁻¹³ m³/s, used in implantable drug-delivery pumps and osmotic mini-pumps for controlled-release pharmacokinetic studies. An Alzet osmotic pump for rodent experiments delivers 0.25-10 µL/h of dissolved drug directly into tissue. 1 µL/h ≈ 2.778×10⁻¹³ 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.
