About Miles per Minute

A mile per minute (mi/min) = exactly 26.8224 m/s = 60 mph. The X-15 rocket plane flew at ~4.5 mi/min (Mach 6.7); the SR-71 Blackbird at ~2.1 mi/min (Mach 3.2). Speed of sound at sea level ≈ 0.77 mi/min. 'Mile-a-minute' (60 mph = 1 mi/min) was a historic railway milestone first achieved on the Great Western Railway in the 1840s. 1 mi/min = 96.5604 km/h.

About Kilometres per Second

A kilometre per second (km/s) = 1,000 m/s - the scale of orbital mechanics and hypervelocity. ISS orbital speed ≈ 7.66 km/s; Earth escape velocity 11.186 km/s. Voyager 1 travels ~17 km/s relative to the Sun. Meteoroids enter Earth's atmosphere at 11-72 km/s; solar wind 400-800 km/s. High-explosive detonation fronts propagate at 6.9-8.8 km/s. 1 km/s = 3,600 km/h = 2,236.9 mph.
