## How to convert kilowatts to amps

How to convert electric power in kilowatts (kW) to electric current in amps (A).

You can calculate amps from kilowatts and volts. You can't convert kilowatts to amps since kilowatts and amps units do not measure the same quantity.

## DC kilowatts to amps calculation formula

The current

Iin amps is equal to 1000 times the powerPin kilowatts, divided by the voltageVin volts:

I_{(A)}= 1000×P_{(kW)}/V_{(V)}So amps are equal to 1000 times kilowatts divided by volts.

amps = 1000

×kilowatts / voltsor

A = 1000 × kW / V

## Example

What is the current in amps when the power consumption is 0.33 kilowatts and the voltage supply is 110 volts?

I= 1000 × 0.33kW / 110V = 3A## AC single phase kilowatts to amps calculation formula

The phase current

Iin amps is equal to 1000 times the real powerPin kilowatts, divided by the power factorPFtimes the RMS voltageVin volts:

I= 1000×P/ (PF×V)So amps are equal to 1000 times kilowatts divided by power factor times volts.

amps = 1000

×kilowatts / (PF× volts)or

A = 1000 × kW / (

PF× V)## Example

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the RMS voltage supply is 110 volts?

I= 1000 × 0.33kW / (0.8 × 110V) = 3.75A## AC three phase kilowatts to amps calculation formula

The phase current

Iin amps is equal to 1000 times the real powerPin kilowatts, divided by square root of 3 times the power factorPFtimes the line to line RMS voltageV_{L-L}in volts:

I= 1000×P/ (√3 ×PF×V_{L-L})So amps are equal to 1000 times kilowatts divided by square root of 3 times power factor times volts.

amps = 1000

×kilowatts / (√3 ×PF× volts)or

A = 1000 × kW / (

√3 ×PF× V)## Example

What is the phase current in amps when the power consumption is 0.33 kilowatts, the power factor is 0.8 and the voltage supply is 110 volts?

I= 1000 × 0.33kW / (√3 × 0.8 × 110V) = 2.165A
