About Inches per Second

An inch per second (in/s) = exactly 0.0254 m/s = 25.4 mm/s. Professional reel-to-reel audio tape runs at 15 or 30 IPS; consumer tape decks at 1⅞ IPS; VHS at ~1.3 IPS. High-speed CNC axes rapid at 800-1,200 in/min ≈ 13-20 in/s. Pneumatic cylinder speeds and robotic end-effector approach speeds in US assembly plants are programmed in in/s. 1 in/s = 0.0254 m/s = 5 ft/min.

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.
