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, but 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 I in amps is equal to 1000 times the power P in kilowatts, divided by the voltage V in volts:
I(A) = 1000 × P(kW) / V(V)
So amps are equal to 1000 times kilowatts divided by volts.
amps = 1000 × kilowatts / volts
or
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 current I in amps is equal to 1000 times the power P in kilowatts, divided by the power factor PF times the voltage V in 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 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 / (0.8 × 110V) = 3.75A
AC three phase kilowatts to amps calculation formula
The current I in amps is equal to 1000 times the power P in kilowatts, divided by square root of 3 times the power factor times the voltage V in volts:
I = 1000 × P / (√3 × PF × V )
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 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
