## How do I convert HP to amps?

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

- Amps = (Horsepower × 746) ÷ Efficiency ÷ Volts.
- Watts = Horsepower × 746.
- Watts = Wattsη
- Amps = Watts ÷ Volts.
- Amps = HP × 746V × η × PF.

## Can amps convert to horsepower?

Multiply amps by volts to obtain the motor’s wattage, or watts (A * V = W). … Divide the wattage by the conversion factor 746 W per HP to convert watts to horsepower. The equation would be as follows: **(W) / (746 W per HP) = HP**. In our example, (575 W) / (746 W per HP) = 0.75 or 3/4 HP.
