About Centimetres per Second
A centimetre per second (cm/s) is 10⁻² m/s - the speed of slow animals, gentle breezes, and lab syringe pumps. Tortoises travel 0.5-1.5 cm/s; the fastest garden snail record is ~1.3 cm/s. A gentle breeze that barely moves leaves is Beaufort 1 ≈ 50-100 cm/s. Drug-delivery syringe pumps run 0.01-10 cm/s. Coarse silt settles in still water at ~0.2 cm/s (Stokes' law). Capacitive touch sensors detect finger motion at 1-10 cm/s. 1 cm/s = 0.01 m/s.
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.
