Conversion number between kilometre per second [km/s] and speed of sound [s] is 2.9188247242297. This means, that kilometre per second is bigger unit than speed of sound.
Switch to reverse conversion:
from speed of sound to kilometre per second conversion
| [km/s] |
Result in speed of sound
?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!

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.
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.
