Conversion number between speed of sound [s] and kilometre per second [km/s] is 0.34260364855033. This means, that speed of sound is smaller unit than kilometre per second.
Switch to reverse conversion:
from kilometre per second to speed of sound conversion
| [s] |
Result in kilometre per second
?If conversion between speed of sound to metre-per-second and metre-per-second to kilometre per second is exactly definied, high precision conversion from speed of sound to kilometre per second 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!

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.
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.
