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.

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.
