How to Convert Kilometers Per Second to Speed Of Sound

Speedometers are used in vehicles to measure speed

To convert a kilometer per second measurement to a speed of sound measurement, multiply the speed by the conversion ratio. One kilometer per second is equal to 2.915452 speed of sound, so use this simple formula to convert:

speed of sound = kilometers per second × 2.915452

The speed in speed of sound is equal to the kilometers per second multiplied by 2.915452.

For example, here's how to convert 5 kilometers per second to speed of sound using the formula above.
5 km/s = (5 × 2.915452) = 14.577259 sound

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

Kilometers Per Second

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

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

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

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.
