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

To convert a speed of sound measurement to a kilometer per hour measurement, multiply the speed by the conversion ratio. One speed of sound is equal to 1,234.8 kilometers per hour, so use this simple formula to convert:

The speed in kilometers per hour is equal to the speed of sound multiplied by 1,234.8.

**For example,**here's how to convert 5 speed of sound to kilometers per hour using the formula above.

Speed of sound and kilometers per hour 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,^{[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.

## Kilometers Per Hour

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

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

In formal expressions, the slash, or solidus (/), is used to separate units used to indicate division in an expression.^{[2]}

Kilometers per hour can be expressed using the formula:

v_{km/s} = d_{km}t_{hr}

The velocity in kilometers per hour is equal to the distance in kilometers divided by time in hours.
