# Convert Knots to Speed Of Sound

Enter the speed in knots below to get the value converted to speed of sound.

**Results in Speed Of Sound:**

## How to Convert Knots to Speed Of Sound

To convert a knot measurement to a speed of sound measurement, multiply the speed by the conversion ratio. One knot is equal to 0.0015 speed of sound, so use this simple formula to convert:

The speed in speed of sound is equal to the knots multiplied by 0.0015.

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

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

## Knots

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.

## 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.
