Centimeter per Hour
cm/h
Definition
The centimeter per hour is a unit of speed representing the distance of one centimeter traveled in one hour. It is used for measuring extremely slow speeds such as the growth rates of plants, the movement of microorganisms, or other biological processes.
History/Origin
Centimeter per hour was developed for measuring very slow biological and geological processes. It became useful in botany, microbiology, and other life sciences where processes occur at rates too slow to measure in larger units.
Current Use
Centimeter per hour is used in biology for measuring plant growth rates, in microbiology for bacterial movement, in geology for very slow erosion processes, and in some industrial applications for extremely slow-moving systems.

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.
