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.
