Conversion number between millimetre per hour [mm/h] and speed of sound [s] is 8.1078464561935 × 10-10. This means, that millimetre per hour is smaller unit than speed of sound.
Switch to reverse conversion:
from speed of sound to millimetre per hour conversion
| [mm/h] |
Result in speed of sound
?If conversion between millimetre per hour to metre-per-second and metre-per-second to speed of sound is exactly definied, high precision conversion from millimetre per hour 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 millimetre per hour unit: ≡ 1 mm / 3600 s. The speed at which the body travels 1 millimetre in 1 hour.
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.
