How to Convert Meters Per Second to Speed Of Light

Speedometers are used in vehicles to measure speed

To convert a meter per second measurement to a speed of light measurement, divide 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:

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

The speed in speed of light is equal to the 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.
500,000,000 m/s = (500,000,000 ÷ 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.

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.[1]

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

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

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.
