# Speed Of Sound to Kilometers Per Second Conversion

Enter the speed in speed of sound below to get the value converted to kilometers per second.

Results in Kilometers Per Second: 1 sound = 0.343 km/s

## How to Convert Speed Of Sound to Kilometers Per Second

To convert a speed of sound measurement to a kilometer per second measurement, multiply the speed by the conversion ratio.

Since one speed of sound is equal to 0.343 kilometers per second, you can use this simple formula to convert:

kilometers per second = speed of sound × 0.343

The speed in kilometers per second is equal to the speed of sound multiplied by 0.343.

For example, here's how to convert 5 speed of sound to kilometers per second using the formula above.
5 sound = (5 × 0.343) = 1.715 km/s

Speed of sound and kilometers per second 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, 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.

## Kilometers Per Second

Kilometers per second are a measurement of speed expressing the distance traveled in kilometers in one second.

The kilometer per second, or kilometre per second, is an SI unit of speed in the metric system. Kilometers per second can be abbreviated as km/s, and are also sometimes abbreviated as km/sec. For example, 1 kilometer per second can be written as 1 km/s or 1 km/sec.

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.

Kilometers per second can be expressed using the formula:
vkm/s = dkm / tsec

The velocity in kilometers per second is equal to the distance in kilometers divided by time in seconds.
