Constant = (62.42 / 550.221) Constant = 0.113491. 1 HorsePower = 746 Watts. To get electricity out of a waterwheel you will have to gear the RPMs of the waterwheel up 300 to 600% and then run it through a generator or a DC motor to charge a battery bank. This will generally cut your power at the axle HP by almost 1/3 to 1/2.
