How to Convert Meters per Second to Speed of Light

To convert a measurement in meters per second to a measurement in speed of light, divide the speed by the following conversion ratio: 299,792,458 meters per second/speed of light.

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

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

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

For example, here's how to convert 500,000,000 meters per second to speed of light using the formula above.

speed of light = (500,000,000 m/s ÷ 299,792,458) = 1.66782 c

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

What Are 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 the expressions of units, the slash, or solidus (/), is used to express a change in one or more units relative to a change in one or more other units.^[1] For example, m/s is expressing a change in length or distance relative to a change in time.

Meters per second can be expressed using the formula:
v_m/s = d_m / t_sec

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

What Is the 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.^[2]

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