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 Yards per Second

A yard per second (yd/s) = exactly 0.9144 m/s - brisk jog speed, natural for American and British sports. American football wide receivers at full sprint: 10-11 yd/s; defensive backs 9-10 yd/s. Ten-pin bowling ball rolls the 20 yd lane in 2-3 s ≈ 7-9 yd/s. A sprinting cricket fielder covers the 22 yd pitch in ~3 s ≈ 7 yd/s. Racing greyhound: ~20 yd/s. 1 yd/s = 0.9144 m/s = 2.04545 mph.
