What this speed conversion is for

Use this page when a measurement is written in speeds of light and the next step needs meters per second. The number stays blank until you press Calculate, so a half-typed entry is never mistaken for the answer.

The factor

Multiply by the factor: 1 speed of light = 2.99792e+08 meters per second.

A worked example

10 speeds of light are 2.99792e+09 meters per second. Multiply the result by the reverse factor if you want the original number back.

How to check it

Write the factor down, do the multiply on paper, and compare it with the result card. If you change a sentence on this page, edit the HTML file and reload. The form and this note live in the same file.

The reverse conversion is meters per second to speeds of light. A nearby pair in the same units is speeds of light to miles per hour. When the converted number is the input to a job, continue with the speed calculator.
