# How to convert Volts to kW

## DC volts to kW calculation formula

P(kW) = I(A) x V(V) / 1000

The power P in kilowatts (kW) is equal to the current I in amps (A), multiplied by the voltage V in volts (V), divided by 1000.

So,

kW = A x V / 1000
kilowatt = amp x volt / 1000

For example:

Current (I) = 2A
Voltage (V) = 25V

Power (P) = 2A x 25V / 1000 = 0,05kW

## AC single phase volts to kW calculation formula

P(kW) = PF × I(A) × V(V) / 1000

The power P in kilowatts (kW) is equal to the power factor PF, multiplied by the phase current I in amps (A), multiplied by the RMS voltage V in volts (V), divided by 1000.

So,

kW = PF x A x V / 1000
kilowatt = PF x amp x volt / 1000

For example:

Current (I) = 2A
Voltage (V) = 25V
PF = 0,6

Power (P) = 0,6 x 2A x 25V / 1000 = 0,03kW

## AC three phase volts to kW calculation formula

P(kW) = √3 × PF × I(A) × VL-L(V) / 1000

The power P in kilowatts (kW) is equal to square root of 3, multiplied by the power factor PF, multiplied by the phase current I in amps (A), multiplied by the line to line RMS voltage VVL-L in volts (V), divided by 1000.

So,

kW = √3 × PF x A x V / 1000
kilowatt = √3 × PF x amp x volt / 1000

For example:

Current (I) = 2A
Voltage (V) = 25V
PF = 0,6

Power (P) = √3 × 0,6 x 2A x 25V / 1000 = 0,052kW
