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.

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.
