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.
Mile/second
A mile per second (mi/s) is a unit of speed representing the distance of one mile traveled in one second.
History/Origin
The mile per second has been used primarily in scientific contexts, especially in astronomy and physics, to measure extremely high velocities such as those of celestial objects. Its usage has been limited due to the convenience of metric units in scientific measurement.
Current Use
Today, the mile per second is mainly used in scientific research, particularly in astrophysics and space science, to describe high-velocity phenomena like the speed of spacecraft, stars, or other celestial bodies.
