About Miles per Hour
A mile per hour (mph) = exactly 0.44704 m/s - the primary road speed unit in the US, UK, and a few other countries. US interstate limits 65-85 mph; UK motorway 70 mph. Walking ~3-4 mph; club cycling 20-25 mph. MLB elite fastball 100 mph (44.7 m/s). Saffir-Simpson Category 5 hurricane ≥157 mph. Boeing 737 MAX cruises at ~521 mph (Mach 0.79). 1 mph = 0.44704 m/s = 1.60934 km/h = 0.86898 kn.
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.
