How do I convert HP to amps?

Converting horsepower to amps can be done in a few simple steps, or using this simple formula.

  1. Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
  2. Watts = Horsepower × 746.
  3. Watts = Wattsη
  4. Amps = Watts ÷ Volts.
  5. Amps = HP × 746V × η × PF.

How do you convert HP volts to amps?

Given horsepower and volts, it is possible to calculate amps. The calculation of amps uses Ohm’s Law, which is amps times volts equals watts. Multiply the horsepower by 746 watts. For example, an engine at two horsepower with 230 volts would be calculated as two horsepower times 746 watts, which equals 1492.
