Conversion Formula
km/s = µm/s × 1.000000000e-9
About Micrometres per Second
A micrometre per second (µm/s) is 10⁻⁶ m/s - the speed of cell motility, bacteria, and precision machining feeds. E. coli swims at 20-30 µm/s; the fastest bacteria (Thiovulum majus) reach 600 µm/s. Neutrophils chasing a chemoattractant move at 10-20 µm/s. Microfluidic lab-on-chip analytical channels flow at 1-1,000 µm/s. Diamond-turning lathe in-feeds for optical surfaces are 1-100 µm/s. Fast glacier centrelines move ~1-10 µm/s (~100 m/year). 1 µm/s = 10⁻⁶ m/s.
About Kilometres per Second
A kilometre per second (km/s) = 1,000 m/s - the scale of orbital mechanics and hypervelocity. ISS orbital speed ≈ 7.66 km/s; Earth escape velocity 11.186 km/s. Voyager 1 travels ~17 km/s relative to the Sun. Meteoroids enter Earth's atmosphere at 11-72 km/s; solar wind 400-800 km/s. High-explosive detonation fronts propagate at 6.9-8.8 km/s. 1 km/s = 3,600 km/h = 2,236.9 mph.
