## How to Convert Speed of Sound to Speed of Light

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

Since one speed of sound is equal to 1.1441E-6 speed of light, you can use this simple formula to convert:

The speed in speed of light is equal to the speed of sound multiplied by 1.1441E-6.

**For example,**here's how to convert 500,000 speed of sound to speed of light using the formula above.

Speed of sound and speed of light are both units used to measure speed. Keep reading to learn more about each unit of measure.

## What is the 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,^{[1]} 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.

## 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.
