## How do I convert HP to amps?

**Convert to Amps**

- Amps = 1 HP × 746 W120 V × .9.
- Amps = 746120 V × .9.
- Amps = 746108.

## How many HP is 15 amps?

At 100% efficiency, the most a 15-amp, 120v outlet in a home circuit can supply is 15 x 120 or 1800w; 1800 divided by 746 equals **2.41 hp**.

## How many amps does a 300 hp motor draw?
