### Calculation process of conversion value

• 1 kilometre per second = (1000) / (342.603648550333) = 2.9188247242297 speed of sound
• 1 speed of sound = (342.603648550333) / (1000) = 0.34260364855033 kilometre per second
• ? kilometre per second × (1000  ("m/s"/"kilometre per second")) / (342.603648550333  ("m/s"/"speed of sound")) = ? speed of sound

### High precision conversion

If conversion between kilometre per second to metre-per-second and metre-per-second to speed of sound is exactly definied, high precision conversion from kilometre per second to speed of sound is enabled.

Since definition contain rounded number(s) too, there is no sense for high precision calculation, but if you want, you can enable it. Keep in mind, that converted number will be inaccurate due this rounding error!

## Details about kilometre per second and speed of sound units:

Convert Kilometre per second to other unit:

### kilometre per second

Definition of kilometre per second unit: ≡ 1 km / 1 s. The speed with which the body moves 1 km in 1 second. The Earth's circulation speed is about 30 km/s.

Convert Speed of sound to other unit:

### speed of sound

Definition of speed of sound unit: ≡ (1.4 x 286 x (20+273.15) )-2. Speed of sound in the air. But this speed varies between 295-340 m/s depending on the air temperature and pressure. From the NASA formula I calculated the speed on sea level at 20°C.
