# How to convert 500 watts to amps

How to convert electric power of 500 watts (W) to electric current in amps (A).

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

### Amps calculation with voltage of 12V DC

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

amp = watt / volt

amps = 500W / 12V = 41.667A

### Amps calculation with voltage of 120V AC

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

amps = watts / (*PF* × volts)

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

amps = 500W / (1 × 120V) = 4.167A

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

amps = 500W / (0.8 × 120V) = 5.208A

### Amps calculation with voltage of 230V AC

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

amps = watts / (*PF* × volts)

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

amps = 500W / (1 × 230V) = 2.174A

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

amps = 500W / (0.8 × 230V) = 2.717A
