How to Convert Centimeters Per Second to Speed Of Light

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

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

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

For example, here's how to convert 50,000,000,000 centimeters per second to speed of light using the formula above.
50,000,000,000 cm/s = (50,000,000,000 ÷ 29,979,245,800) = 1.66782 c

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

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.[1]

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.

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.
