About Mach and Meters per Second
Mach number expresses speed as a multiple of the speed of sound, taken here as 343 meters per second, the value in dry air at 20 °C at sea level. Supersonic aircraft and missiles are rated in Mach. The meter per second is the SI derived unit of speed. Physics, wind reporting in many countries, and sprint analysis use it directly, and every other speed unit converts through it. One Mach equals 343 Meters per Second (1 mach = 343 mps). Mach is used in supersonic aircraft speeds and in aerospace engineering. Meters per Second is used in physics calculations.
Precision and Rounding:Most speed factors are exact because they derive from exact length and time definitions (1 mph = 1.609344 km/h precisely); Mach is the exception, since the speed of sound varies with temperature and altitude. The figure used here is 343 m/s, the sea-level value at 20 °C. One decimal place covers driving and running; aviation and ballistics carry more.
Conversion factors per NIST Special Publication 811 and the BIPM SI Brochure (9th edition) (reference).
