kn = µm/s × 1.943844492e-6
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 Knots
A knot (kn) = 1 nautical mile per hour = 1,852/3,600 m/s ≈ 0.51444 m/s - the universal speed unit for aviation and maritime navigation (ICAO and IMO standard). GA aircraft cruise 100-140 kn; commercial airliners 450-480 kn; Concorde 1,176 kn (Mach 2). Container ships 18-22 kn; QM2 exceeds 30 kn. Beaufort Force 12 hurricane begins at 64 kn. Gulf Stream surface current 2-4 kn. 1 kn = 1.852 km/h = 1.15078 mph.
