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
Speed of sound and knots 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 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.
