### Calculation process of conversion value

• 1 running speed = (3.94) / (1000) = 0.00394 kilometre per second
• 1 kilometre per second = (1000) / (3.94) = 253.80710659898 running speed
• ? running speed × (3.94  ("m/s"/"running speed")) / (1000  ("m/s"/"kilometre per second")) = ? kilometre per second

### High precision conversion

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