Do you want to convert knots to speed of sound?

## How to Convert Speed of Sound to Knots

To convert a measurement in speed of sound to a measurement in knots, multiply the speed by the following conversion ratio: 666.738661 knots/speed of sound.

Since one speed of sound is equal to 666.738661 knots, you can use this simple formula to convert:

knots = speed of sound × 666.738661

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

For example, here's how to convert 5 speed of sound to knots using the formula above.
knots = (5 sound × 666.738661) = 3,333.693305 kn

## 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 a Knot?

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.
