### Calculation process of conversion value

• 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

### High precision conversion

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!
