Mach (Si Standard)
The Mach number is a dimensionless unit representing the ratio of an object's speed to the speed of sound in the surrounding medium.
History/Origin
Named after the Austrian physicist Ernst Mach, the Mach number was introduced in the early 20th century to describe supersonic and hypersonic speeds, initially used in aerodynamics and fluid dynamics research.
Current Use
The Mach number is widely used in aeronautics and astronautics to specify aircraft and spacecraft speeds relative to the local speed of sound, especially in high-speed flight regimes.
Kilometer/minute
Kilometer per minute (km/min) is a unit of speed representing the distance of one kilometer traveled in one minute.
History/Origin
The kilometer per minute has been used primarily in contexts requiring rapid measurement of speed, such as in transportation and engineering, though it is less common than units like km/h or m/s. Its usage has declined with the adoption of standardized SI units.
Current Use
Today, km/min is mainly used in specialized fields like aviation, military, or scientific calculations where high-speed measurements are relevant, but it is not a standard unit in everyday measurements or most international standards.
