Conversion number between **speed of sound** [s] and
**kilometre per hour** [km/h] is **1233.3731347812**.
This means, that speed of sound is bigger unit than kilometre per hour.

Switch to reverse conversion:

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

[s] |

Result in **kilometre per hour**

- 1 speed of sound = `(342.603648550333) / ((1000/3600))` =
**1233.3731347812**kilometre per hour - 1 kilometre per hour = `((1000/3600)) / (342.603648550333)` =
**0.00081078464561935**speed of sound - ? speed of sound × `(342.603648550333 ("m/s"/"speed of sound")) / ((1000/3600) ("m/s"/"kilometre per hour"))` =
**?**kilometre per hour

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

Convert **Kilometre per hour to other unit:**

### kilometre per hour

Definition of kilometre per hour unit: ≡ 1 km / 3600 s. km/h in everyday life is the most commonly used speed unit (in Europe). Interpretation: The speed with which the body travels 1 kilometre in 1 hour. The number on traffic signs indicating speed limits is also in this unit of measure.
