About Microlitres per second

The microlitre per second (µL/s) equals 10⁻⁹ m³/s, the working range of microfluidic lab-on-a-chip devices and nano-HPLC pumps. Organ-on-a-chip perfusion bioreactors, droplet microfluidic systems, and capillary electrophoresis instruments operate at 0.1-100 µL/s. A syringe pump delivering 0.36 mL/h produces exactly 0.1 µL/s. 1 µL/s = 10⁻⁹ m³/s = 60 µL/min.

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.
