Convert the speed of light to kilometers per second

Explanation

From this page you can convert the speed of light to kilometers per second (or c to km/s) simply, by using the application above.

In case you are wondering, to convert from the speed of light to kilometers per second you need to multiply by 299792.458. This factor is calculated using the respective definitions of the two units you can find below.

Formula

1 c=299792.458 km/s

dimension	speed
symbol	c

This unit represents the speed of light in vacuum (c).

The particules that make up light, the photons, are masseless, and when they travel in a medium devoid of other particle, they do it at the maximum speed possible in the universe.

Also, according to Einstein and the theory of relativity, the speed of light is absolute. The relative movement of the light source or the observer will not change its measured value.

Value

The speed of light in vacuum is 299792458 meters per second.

Equivalences

The speed of light is equivalent to:

Some Facts

Right now you are traveling around the Sun at approximately 0.0001 times the speed of light.
The Large Hadron Collider near Geneva can accelerate protons at a speed only 3.1 m/s below the speed of light. At that speed, each individual proton has the kinetic energy of a flying mosquito.
Since 1983, the meter is defined in terms of the speed of light.
