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 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.
