Conversion number between speed of sound [s] and feet per second [fps] is 1124.027718341. This means, that speed of sound is bigger unit than feet per second.
Switch to reverse conversion:
from feet per second to speed of sound conversion
| [s] |
Result in feet per second
?If conversion between speed of sound to metre-per-second and metre-per-second to feet per second is exactly definied, high precision conversion from speed of sound to feet 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 feet per second unit: ≡ 1 ft / 1 s = 30.48 cm / 1 s. Abbreviation is fps. In America, perhaps this is the second most commonly used speed unit in public life (after miles per hour). Definition: The speed at which the body moves 1 foot (or 30.48 centimetres) in 1 second.
