Velocity of Light in Vacuum
c
Definition
The velocity of light in vacuum is the speed at which light travels in a vacuum, approximately 299,792,458 meters per second. It is a fundamental physical constant and the maximum speed at which all energy, matter, and information can travel in the universe.
History/Origin
The velocity of light was first measured by Ole Rømer in 1676, but its exact value was refined over centuries. In 1983, the meter was redefined in terms of the speed of light, making it a fundamental constant of nature with an exact value.
Current Use
The velocity of light is used in physics, astronomy, telecommunications, and various scientific applications. It is fundamental to Einstein's theory of relativity and is used in GPS systems, fiber optic communications, and astronomical calculations.

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.
