Torque is not force x distance. It's force x radius, since torque only applies to rotation about an axis.

Work (Joules) is force x distance which is also equal to torque x radians (1 revolution = 2pi radians)

Power (watts) is work / time.

Since velocity = distance / time, velocity x force = watts

Write this down on a piece of paper. It is very simple math.

Also, 1HP = 746 watts = 550 ft-lb/sec
1ft-lb (work) = 1.35 Joules
1lb-ft (torque) = 1.35 Newton-meters
1 Newton = 4.45 lbs
1 Meter = 3.28 ft
