## Definition

The **Speed of Light** (or * c*) is the speed at which a photon (an "energy packet" of electromagnetic radiation) travels in a vacuum.

### Values

The exact measurement for the speed of light is 299,792,458 meters per second, in the following values, the speed of light will use values based on the rounded 300,000,000 m/s.

Meters per second:

Kilometers per second:

Miles per second:
