**speed of sound** [s] is **0.0013048314047196**.
This means, that miles per hour is smaller unit than speed of sound.

Switch to reverse conversion:

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

[mph] |

Result in **speed of sound**

- 1 miles per hour = `(0.44704) / (342.603648550333)` =
**0.0013048314047196**speed of sound - 1 speed of sound = `(342.603648550333) / (0.44704)` =
**766.38253523249**miles per hour - ? miles per hour × `(0.44704 ("m/s"/"miles per hour")) / (342.603648550333 ("m/s"/"speed of sound"))` =
**?**speed of sound

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

### miles per hour

Definition of miles per hour unit: ≡ 1 mi / 3600 s = 1609.344 m / 3600 s. In American public life, this is the most commonly used speed unit. Cars speeds are measured in mpg. Interpretation: The speed at which the body moves 1 mile (or 1609.344 metres) in 1 hour.

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.
