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.
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.
