## How to Convert Speed Of Light to Speed Of Sound

To convert a speed of light measurement to a speed of sound measurement, multiply the speed by the conversion ratio.

Since one speed of light is equal to 874,030.489796 speed of sound, you can use this simple formula to convert:

The speed in speed of sound is equal to the speed of light multiplied by 874,030.489796.

**For example,**here's how to convert 5 speed of light to speed of sound using the formula above.

Speed of light and speed of sound 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.

## Speed Of Sound

The speed of sound is the distance a sound wave travels through an elastic medium.
The speed of sound through air at 20 °C is equal to 343 meters per second,^{[2]} or roughly 767 miles per hour.

Speed of sound can be abbreviated as *sound*; for example, 1 speed of sound can be written as 1 sound.
