How to Convert Knots to Speed of Sound
To convert a measurement in knots to a measurement in speed of sound, multiply the speed by the following conversion ratio: 0.0015 speed of sound/knot.
Since one knot is equal to 0.0015 speed of sound, you can use this simple formula to convert:
speed of sound = knots × 0.0015
The speed in speed of sound is equal to the speed in knots multiplied by 0.0015.
For example, here's how to convert 500 knots to speed of sound using the formula above.
speed of sound = (500 kn × 0.0015) = 0.749919 sound
Knots and speed of sound are both units used to measure speed. Keep reading to learn more about each unit of measure.
What Is a Knot?
One knot is equal to a speed of one nautical mile per hour,[1] 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.

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,[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.
