# How to convert 10 amps to watts

How to convert electric current of 10 amps (A) to electric power in watts (W).

You can calculate (but not convert) the watts from amps and volts:

### 10A to watts calculation with voltage of 12V DC

For DC power supply, watts are equal to amps times volts.

watts = amps × volts

watts = 10A × 12V = 120W

### 10A to watts calculation with voltage of 120V AC

For AC power supply, watts are equal to the power factor times amps times volts.

watts = PF × amps × volts

For resistive load without inductors or capacitors, the power factor is equal to 1:

watts = 1 × 10A × 120V = 1200W

For inductive load (like induction motor), the power factor can be approximately equal to 0.8:

watts = 0.8 × 10A × 120V = 960W

### 10A to watts calculation with voltage of 230V AC

For AC power supply, watts are equal to the power factor times amps times volts.

watts = PF × amps × volts

For resistive load without inductors or capacitors, the power factor is equal to 1:

watts = 1 × 10A × 230V = 2300W

For inductive load (like induction motor), the power factor can be approximately equal to 0.8:

watts = 0.8 × 10A × 230V = 1840W
