About mach
Mach is a dimensionless speed unit named after Austrian physicist Ernst Mach. Mach 1 equals the speed of sound in the surrounding medium, which varies with temperature and altitude. At sea level and 15°C, Mach 1 is approximately 340.3 m/s (1,225 km/h). Mach numbers are essential in aeronautics, rocketry, and fluid dynamics.
