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 Metres per Second
The metre per second (m/s) is the SI unit of speed. Brisk walking ~1.4 m/s; Usain Bolt's peak sprint ~12.4 m/s; speed of sound in air at 20°C 343.2 m/s; in water 1,481 m/s. Rifle muzzle velocities 370-1,200 m/s. Speed of light = exactly 299,792,458 m/s (the defined constant from which the metre is derived since 1983). 1 m/s = 3.6 km/h = 2.23694 mph = 1.94384 kn.
