Conversion number between furlong per fortnight [fur/fn] and speed of sound [s] is 4.854283499701 × 10-7. This means, that furlong per fortnight is smaller unit than speed of sound.
Switch to reverse conversion:
from speed of sound to furlong per fortnight conversion
| [fur/fn] |
Result in speed of sound
?If conversion between furlong per fortnight to metre-per-second and metre-per-second to speed of sound is exactly definied, high precision conversion from furlong per fortnight 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 furlong per fortnight unit: ≡ (mi/8) / 14 days = 201.168 m / (14x86400 s). This is a kind of funny speed unit based on unusual length and time units. Furlong is equal to eighth of mile. Fortnight is 2 weeks time (= 14 days). Two quotients give the fur/fn speed.
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.
