Horsepower to Amps Calculator
Estimate the current drawn by an electric motor from horsepower, voltage, efficiency and power factor.
Enter your values and press Calculate.
How to use the Horsepower to Amps calculator
For conductor and overload sizing use the full-load current tables in your electrical code, not this estimate.
Formula
I = hp × 746 ÷ (V × efficiency × PF) (× 1/√3 for three phase).
