# How to convert 800 watts to amps

How to convert electric power of 800 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 = 800W / 12V = 66.667A

### 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 = 800W / (1 × 120V) = 6.667A

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

amps = 800W / (0.8 × 120V) = 8.333A

### 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 = 800W / (1 × 230V) = 3.478A

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

amps = 800W / (0.8 × 230V) = 4.348A

### Watt definition

Watt is the unit of power (symbol: W).

The watt unit is named after James Watt, the inventor of the steam engine.

One watt is defined as the energy consumption rate of one joule per second.

1W = 1J / 1s

One watt is also defined as the current flow of one ampere with voltage of one volt.

1W = 1V × 1A

### Ampere definition

Ampere or amp (symbol: A) is the unit of electrical current.

The Ampere unit is named after Andre-Marie Ampere, from France.

One Ampere is defined as the current that flows with electric charge of one Coulomb per second.

1 A = 1 C/s
