Conversion number between speed of sound [s] and miles per day [mpd] is 18393.18084558. This means, that speed of sound is bigger unit than miles per day.
Switch to reverse conversion:
from miles per day to speed of sound conversion
| [s] |
Result in miles per day
?If conversion between speed of sound to metre-per-second and metre-per-second to miles per day is exactly definied, high precision conversion from speed of sound to miles per day 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 miles per day unit: ≡ 1 mi / 86400 s = 1609.344 m / 86400 s. The speed with which the body moves 1 mile (or 1609.344 metres) in 1 day.
