## 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)} × V_{L-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 **V**_{VL-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*
