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.
About Nautical Miles per Second
A nautical mile per second (nmi/s) equals exactly 1,852 m/s - squarely in the hypersonic domain at approximately Mach 5.44 (ISA sea level). At this speed, kinetic energy per kilogram is ½ × 1852² ≈ 1.71 MJ/kg, comparable to a small shaped-charge detonation. Ballistic missile re-entry vehicles descend at roughly 3.8-7 nmi/s during the terminal phase; ICBM warheads at peak re-entry travel near 4-6 nmi/s. The US Navy's electromagnetic railgun programme aimed to accelerate 10 kg projectiles to approximately 1.7-2.5 nmi/s in test firings, giving them sufficient kinetic energy to destroy armoured targets without a warhead. Hypervelocity impact experiments at two-stage light-gas gun facilities reach similar speeds to simulate asteroid-impact cratering physics. The speed of sound in beryllium metal (the fastest known bulk acoustic medium) is approximately 12.9 nmi/s. 1 nmi/s = 1,852 m/s = 6,667.2 km/h = 3,600 kn ≈ Mach 5.44.
