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.
About Feet per Second
A foot per second (ft/s) = exactly 0.3048 m/s - the primary speed unit in US ballistics, hydraulics, and gas dynamics. .308 Winchester muzzle velocity ~2,750 ft/s; 9mm pistol 1,200-1,400 ft/s; .50 BMG 2,910 ft/s. Speed of sound at sea level 1,116 ft/s. River channel mean velocities 0.5-6 ft/s; NFPA sprinkler pipe flows also in ft/s. 1 ft/s = 0.3048 m/s = 1.09728 km/h = 60 ft/min.
