About Mach 1
Mach 1 = the speed of sound in dry air at ISA sea-level (15°C, 101.325 kPa) = exactly 340.29 m/s (1,225 km/h; 761 mph). Chuck Yeager first exceeded it on 14 October 1947 in the Bell X-1. At 35,000 ft cruise altitude (−56.5°C), it falls to 295.1 m/s. Flight regimes: subsonic
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.
