    Incidentally, entering "3/4 hp watts" into Google gets you a very quick answer. Google is pretty great at interpreting conversion requests.

  • What purpose do you need this wattage number for? Load calcs? Generator sizing? Oct 11, 2018 at 1:21
  • Note that the rated power of a motor is generally output power. Input power will be higher, depending on power factor, and input VA will be higher again. Oct 11, 2018 at 6:49

A simple conversion is 1 HP = 750 watts, so 3/4 HP is about 560W


There are lots of conversions sites and also found this handy site with a table. There also should be a nameplate on the motor that gives watts or startng watts.
