Unit History
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.
About kilometer per hour
Kilometers per hour became popular as nations adopted the metric system for road networks. It is still the standard unit on speed limits and vehicle dashboards across most of the world.
