You multiply seconds with seconds per hour and somehow get “per hour” as the final result? But even ignoring that error, what is W/h supposed to be? Rate of change of power?
Also, it is a small k for kilo and you don’t write it as 4.31018[unit]. Just 4.310^18 [unit]. Or 4.3E18 [unit].
Colour is worse. No way. It is color you little shit.
