Conversion number between **miles per day** [mpd] and
**speed of sound** [s] is **5.4367975196651 × 10 ^{-5}**.
This means, that miles per day is smaller unit than speed of sound.

Switch to reverse conversion:

from **speed of sound** to **miles per day** conversion

[mpd] |

Result in **speed of sound**

- 1 miles per day = `((1609.344/86400)) / (342.603648550333)` =
**5.4367975196651 × 10**speed of sound^{-5} - 1 speed of sound = `(342.603648550333) / ((1609.344/86400))` =
**18393.18084558**miles per day - ? miles per day × `((1609.344/86400) ("m/s"/"miles per day")) / (342.603648550333 ("m/s"/"speed of sound"))` =
**?**speed of sound

If conversion between **miles per day to metre-per-second** and **metre-per-second to speed of sound** is exactly definied, high precision conversion from miles 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!

Convert **Miles per day to other unit:**

### miles per day

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.

Convert **Speed of sound to other unit:**

### speed of sound

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.
