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.

Kilometer per Second
km/s
Definition
The kilometer per second is a unit of speed representing the distance of one kilometer traveled in one second. It is used for measuring extremely high speeds such as those of spacecraft, projectiles, or other high-velocity objects in physics and engineering.
History/Origin
Kilometer per second was developed for measuring extremely high velocities in physics, astronomy, and aerospace engineering. It became essential for expressing speeds of spacecraft, satellites, and other high-velocity objects in space exploration.
Current Use
Kilometer per second is used in aerospace engineering for spacecraft velocities, in physics for high-speed particle studies, in astronomy for celestial object speeds, and in military applications for projectile velocities.
