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:

c=3×108ms1

Kilometers per second:

c=3×105kms1

Miles per second:

c=1.9×105mis1
