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 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.
