## How to Convert Speed Of Sound to Knots

To convert a speed of sound measurement to a knot measurement, multiply the speed by the conversion ratio. One speed of sound is equal to 666.738661 knots, so use this simple formula to convert:

The speed in knots is equal to the speed of sound multiplied by 666.738661.

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

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

## 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.

## Knots

One knot is equal to a speed of one nautical mile per hour,^{[2]} or one minute of latitude per hour.

Knots can be abbreviated as *kn*, and are also sometimes abbreviated as *kt*. For example, 1 knot can be written as 1 kn or 1 kt.
