### 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!
