How to Convert Speed Of Light to Meters Per Second

To convert a speed of light measurement to a meter per second measurement, multiply the speed by the conversion ratio.

Since one speed of light is equal to 299,792,458 meters per second, you can use this simple formula to convert:

meters per second = speed of light × 299,792,458

The speed in meters per second is equal to the speed of light multiplied by 299,792,458.

For example, here's how to convert 5 speed of light to meters per second using the formula above.
5 c = (5 × 299,792,458) = 1,498,962,290 m/s

Speed of light and meters per second are both units used to measure speed. Keep reading to learn more about each unit of measure.

Speed Of Light

The speed of light is equal to exactly 299,792,458 meters per second, or 670,616,629 miles per hour. The definition of the speed of light is actually derived from the most recent 1983 international definition of the meter.[1]

Speed of light can be abbreviated as c; for example, 1 speed of light can be written as 1 c.

Meters Per Second

Meters per second are a measurement of speed expressing the distance traveled in meters in one second.

The meter per second, or metre per second, is the SI derived unit for speed in the metric system. Meters per second can be abbreviated as m/s, and are also sometimes abbreviated as m/sec. For example, 1 meter per second can be written as 1 m/s or 1 m/sec.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.[2]

Meters per second can be expressed using the formula:
vm/s = dm / tsec

The velocity in meters per second is equal to the distance in meters divided by time in seconds.
