Calculation process of conversion value

1 speed of light = (exactly) `(299792458) / (1000)` = 299792.458 kilometre per second
1 kilometre per second = (exactly) `(1000) / (299792458)` = 3.3356409519815 × 10^-6 speed of light
? speed of light × `(299792458 ("m/s"/"speed of light")) / (1000 ("m/s"/"kilometre per second"))` = ? kilometre per second

High precision conversion

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