I thought it was 746 watts=1 hp.
My old age and memory could be failing me.
This of course is assuming a perfect conversion. The energy of 1 HP and the 746 watts are equal. Converting between them has losses.
A 746 Watt electric motor won't put out 1 HP of shaft power. Some energy will leave as noise, heat, vibration, air flow magnetic flux incuced currents in sourroundings, radiated RFI/EMI, Etc.
