How to Convert Kilometers Per Hour to Speed Of Sound

conversion scale showing kilometers per hour and equivalent speed of sound speed values

To convert a kilometer per hour measurement to a speed of sound measurement, multiply the speed by the conversion ratio. One kilometer per hour is equal to 0.00081 speed of sound, so use this simple formula to convert:

speed of sound = kilometers per hour × 0.00081

The speed in speed of sound is equal to the kilometers per hour multiplied by 0.00081.

For example, here's how to convert 5 kilometers per hour to speed of sound using the formula above.
5 km/h = (5 × 0.00081) = 0.004049 sound

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

Kilometers Per Hour

Kilometers per hour are a measurement of speed expressing the distance travelled 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.

Kilometers per hour can be expressed using the formula:
vkm/s = dkmthr

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

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.
