### Calculation process of conversion value

• 1 kilometre per day = (exactly) ((1000/86400)) / (299792458) = 3.8606955462749 × 10-11 speed of light
• 1 speed of light = (exactly) (299792458) / ((1000/86400)) = 25902068371.2 kilometre per day
• ? kilometre per day × ((1000/86400)  ("m/s"/"kilometre per day")) / (299792458  ("m/s"/"speed of light")) = ? speed of light

### High precision conversion

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