About Knots
A knot (kn) = 1 nautical mile per hour = 1,852/3,600 m/s ≈ 0.51444 m/s - the universal speed unit for aviation and maritime navigation (ICAO and IMO standard). GA aircraft cruise 100-140 kn; commercial airliners 450-480 kn; Concorde 1,176 kn (Mach 2). Container ships 18-22 kn; QM2 exceeds 30 kn. Beaufort Force 12 hurricane begins at 64 kn. Gulf Stream surface current 2-4 kn. 1 kn = 1.852 km/h = 1.15078 mph.
About Mach 5
Mach 5 ≈ 1,701.45 m/s (6,125 km/h) at ISA sea level - the conventional supersonic/hypersonic boundary. Above Mach 5, stagnation temperatures exceed 1,500°C, air dissociates around the vehicle, and ablative thermal protection becomes mandatory. Space Shuttle re-entered at Mach 25; Soyuz capsules at Mach 27; ICBM warheads at Mach 15-25. NASA X-43A scramjet reached Mach 9.6 (air-breathing record, 2004). 1 Mach 5 = 1,701.45 m/s.
