How to Convert Amps to Kilowatts

The conversion from amps to kilowatts depends on the circuit type:

DC Circuits

For DC circuits, use the formula: P(kW) = I × V ÷ 1000

  • P = Power in kilowatts (kW)
  • I = Current in amperes (A)
  • V = Voltage in volts (V)

AC Single Phase

For AC single-phase circuits: P(kW) = I × V × PF ÷ 1000

AC Three Phase

For AC three-phase circuits: P(kW) = I × V × PF × √3 ÷ 1000
