Conversion number between feet per day [fpd] and speed of sound [s] is 1.0296964999366 × 10-8. This means, that feet per day is smaller unit than speed of sound.
Switch to reverse conversion:
from speed of sound to feet per day conversion
| [fpd] |
Result in speed of sound
?If conversion between feet per day to metre-per-second and metre-per-second to speed of sound is exactly definied, high precision conversion from feet per day 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 feet per day unit: ≡ 1 ft / 86400 s = 30.48 cm / 86400 s. The speed with which the body travels 1 foot (or 30.48 centimetres) in 1 day.
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.
