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.
About Nanometres per Second
A nanometre per second (nm/s) is 10⁻⁹ m/s - the speed of atomic-scale processes. AFM tips scanning surfaces move at 1-100 nm/s to resolve atomic steps. Kinesin molecular motors walk along microtubules at ~1,000-8,000 nm/s, stepping 8 nm per ATP cycle. Piezoelectric nano-positioners in electron microscopes and gravitational-wave interferometers are driven at nm/s for sub-nanometre position control. Crystal growth in solution can proceed at 1-10 nm/s under controlled conditions. 1 nm/s = 10⁻⁹ m/s.
