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.
Mach (20°c, 1 Atm)
Mach is a unit of speed representing the ratio of an object's speed to the speed of sound in the surrounding medium, typically at 20°C and 1 atm pressure.
History/Origin
Named after physicist Ernst Mach, the Mach number was developed in the early 20th century to describe speeds relative to the speed of sound, especially in aeronautics and fluid dynamics.
Current Use
Mach is widely used in aeronautics and astronautics to express aircraft and spacecraft speeds, particularly in high-speed flight and supersonic travel contexts.
