mi/s = µm/s × 6.213711922e-10
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 Miles per Second
A mile per second (mi/s) = exactly 1,609.344 m/s - above the fastest air-breathing aircraft. NASA X-43A scramjet: 2.9 km/s ≈ 1.8 mi/s (Mach 9.6). Earth's orbital speed around the Sun: ~18.5 mi/s (29.8 km/s). Light travels ~186,282 mi/s in vacuum - the classic imperial figure still used in popular astronomy. Tunguska impactor entered Earth's atmosphere at ~9-11 mi/s. 1 mi/s = 3,600 mph = 3,128.3 kn.
