Using Ohm's law this is a relatively simple question to answer...

1 horsepower = 745.7 watts


Alas, this assumes 100% efficiency, which saws are not. For example, my
2HP saw is rated to draw 9A @ 220 or 1980W, considerably more then the
1492W ideal rating. It is this that makes me shy from 2HP+ tools; don't
wanna run 220 all over the shop. Though a 2HP DC is calling me...

you guys are starting to get there, but whats so hard about looking on the
motor for the current rating or calling the manufacturer and getting a power
factor curve for it if you insist on going that route?
