## How do I convert kW to amps?

To convert amps to kilowatts the power formula can be used, which states that I = P ÷ E, given that P is the power in watts, I is current in amps, and E is voltage in volts. Thus, the power P in kilowatts is equal to the current I in amps multiplied by the voltage V in volts, divided by 1,000.

## How do you calculate amps on a motor?

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.
