This Amps to Kilowatts calculator to convert Amps & volts value into power result in Kilowatts, select your current type (DC/AC), insert amps and voltage, then press Calculate to get the power result in kW. Swap kW to Amps calculator.

### How to Calculate Amps to Kilowatts

AC, DC Amps to Kilowatts manual calculation

**Amps (DC) to kW formula:**

P(kW) = I(A) × V(V) / 1000

Power (P) in kilowatts equal to current (A) amps, multiplied by voltage in (V) volts divided by 1000.

**Amps (AC single phase) to kW formula:**

P(kW) = PF × I(A) × V(V) / 1000

Power (P) in kilowatts equal to Power Factor (PF), multiplied by current I (A) amps, multiplied by voltage in (V) volts divided by 1000.

**Amps (AC three phase) to kW formula:**

Line to line voltage

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

Line to neutral voltage

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

**(PF) Power Factor values:**

Device | Typical power factor |
---|---|

Resistive load | 1 |

Fluorescent lamp | 0.95 |

Incandescent lamp | 1 |

Induction motor full load | 0.85 |

Induction motor no load | 0.35 |

Resistive oven | 1 |

Synchronous motor | 0.9 |

*For accurate calculations do not use typical power factor values.
