Mach (20°C, 1 atm)
Ma
Definition
Mach at 20°C and 1 atmosphere is the speed of sound in air under these specific conditions, approximately 343.6 meters per second. It is used as a reference for measuring high speeds, particularly in aviation and aerospace applications.
History/Origin
The Mach number was named after Austrian physicist Ernst Mach and became the standard for measuring high speeds in aviation. It represents the ratio of an object's speed to the speed of sound in the surrounding medium.
Current Use
Mach is used in aviation for measuring aircraft speeds, in aerospace engineering for high-speed vehicle design, and in various applications involving high-speed motion. It is particularly important for supersonic and hypersonic flight.

Millimeter per Hour
mm/h
Definition
The millimeter per hour is a unit of speed representing the distance of one millimeter traveled in one hour. It is used for measuring extremely slow speeds such as the growth rates of crystals, the movement of tectonic plates, or other very slow processes.
History/Origin
Millimeter per hour was developed for measuring extremely slow geological and biological processes. It became essential in crystallography, geology, and other sciences where processes occur at rates too slow to measure in larger units.
Current Use
Millimeter per hour is used in geology for measuring tectonic plate movement, in crystallography for crystal growth rates, in some biological studies for very slow growth processes, and in precision manufacturing applications.
