Electric Horsepower Calculator - CalcuNation

To find the electric horsepower of a motor, use the equation: Horsepower = (Volts x Amps) / 745.7. (does not take efficiency into consideration) Example: The electric horsepower of a motor with 120 volts. and 10 amps is: HP = (120 x 10) / 745.7. Calculated out this gives an electric horsepower of 1.6092. (rounded to the nearest 10,000th)

Horsepower to Amps Calculator - Inch Calculator

The first step to convert HP to amps is convert HP to watts. Since 1 HP is equal to 746 W simply multiply the horsepower by 746 for this conversion. Watts = Horsepower × 746. Account for Efficiency. Since motors are not efficient, the number of amps needed to achieve the power output is actually higher depending on the efficiency.
