About Kilometres per Hour
A kilometre per hour (km/h) = 1/3.6 m/s - the universal road speed unit across most of the world. Walking pace ~5-6 km/h; jogging 9-12 km/h; elite marathon runners average 20-21 km/h. High-speed rail (TGV, Shinkansen, ICE) 250-350 km/h; TGV record 574.8 km/h. Category 5 hurricane ≥252 km/h; Thrust SSC land speed record 1,228 km/h (Mach 1.02). 1 km/h = 0.2778 m/s = 0.6214 mph = 0.5400 kn.
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.
