Unit History
About knot
The knot originated with sailors gauging speed using knotted ropes. Equal to one nautical mile per hour, it is still essential in maritime and aviation navigation.
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.
