How to Convert Speed Of Light to Centimeters Per Second

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

Since one speed of light is equal to 29,979,245,800 centimeters per second, you can use this simple formula to convert:

centimeters per second = speed of light × 29,979,245,800

The speed in centimeters per second is equal to the speed of light multiplied by 29,979,245,800.

For example, here's how to convert 5 speed of light to centimeters per second using the formula above.
5 c = (5 × 29,979,245,800) = 149,896,229,000 cm/s

Speed of light and centimeters 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.

Centimeters Per Second

Centimeters per second are a measurement of speed expressing the distance traveled in centimeters in one second.

The centimeter per second, or centimetre per second, is an SI unit of speed in the metric system. Centimeters per second can be abbreviated as cm/s, and are also sometimes abbreviated as cm/sec. For example, 1 centimeter per second can be written as 1 cm/s or 1 cm/sec.

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

Centimeters per second can be expressed using the formula:
vm/s = dcm / tsec

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