Calculation process of conversion value

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

High precision conversion

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

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.

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.
