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.

About Centimetres per Second

A centimetre per second (cm/s) is 10⁻² m/s - the speed of slow animals, gentle breezes, and lab syringe pumps. Tortoises travel 0.5-1.5 cm/s; the fastest garden snail record is ~1.3 cm/s. A gentle breeze that barely moves leaves is Beaufort 1 ≈ 50-100 cm/s. Drug-delivery syringe pumps run 0.01-10 cm/s. Coarse silt settles in still water at ~0.2 cm/s (Stokes' law). Capacitive touch sensors detect finger motion at 1-10 cm/s. 1 cm/s = 0.01 m/s.
