Convert amps to horsepower using an easy calculator and learn the formulas to convert electrical power in horsepower yourself.
This calculator estimates the crucial full load amps (FLA) your motor will draw at its rated horsepower. Enter the motor’s voltage (line-to-line voltage between any two phases) and horsepower. For a more precise calculation, include the motor’s efficiency (typically 90-95%).
