Power = work/time

Work = Force * Distance (ie Newtons * meters (Nm) )

Nm = Joule = J

Power = J/second = J/S = Watt

1 Horsepower = 746watts = 746N * 1m / 1s = 166lbf * 3.28ft / 1s

1 HP = 546lb * 1ft / 1s

So... if you can lift a 546lb weight straight up a distance of 1ft in 1 second then you are outputing 1HP. OR 273lb up 1ft in 1/2 second..... or something like that.

Just thought I would add some confusion by properly defining some terms being thrown around here.
