About Kilometres per Minute

A kilometre per minute (km/min) = 50/3 m/s ≈ 16.667 m/s. F1 cars at Monza average ~4.33 km/min in qualifying. High-speed trains (TGV, ICE) cruise at 2.5-3.5 km/min. Subsonic military jet trainers fly at 3-7 km/min; combat aircraft cruise at 7-10 km/min. Dead-reckoning navigation: elapsed minutes × km/min = distance. 1 km/min = 60 km/h = 37.28 mph.

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.
