Also, we would only ever report W or mW as the SI unit, the choose is
ours and whatever we choose requires adjusting of the reported rapl
scalefactor. Since we measure in seconds, the rapl scalefactor itself
would have to convert from horsepower into J for the results to make
sense, and defined that way.
