maybe it will help to understand that horsepower is a measure of power, not
force - torque is "force", RPM is "speed", power is the product, so to
speak. one horsepower is 3300 ft-lbs per minute - e.g. a one horsepower
motor can lift a 3300 pound weight (not mass) one foot in one minute, or it
can lift a 1 pound weight about 2/3 of a mile in the same time.

Ya dropped a zero. 1 HP = 33,000 ft-lbf/min.
