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.

About Yards per Second

A yard per second (yd/s) = exactly 0.9144 m/s - brisk jog speed, natural for American and British sports. American football wide receivers at full sprint: 10-11 yd/s; defensive backs 9-10 yd/s. Ten-pin bowling ball rolls the 20 yd lane in 2-3 s ≈ 7-9 yd/s. A sprinting cricket fielder covers the 22 yd pitch in ~3 s ≈ 7 yd/s. Racing greyhound: ~20 yd/s. 1 yd/s = 0.9144 m/s = 2.04545 mph.
