Formula & Calculation Steps:
kW = (VA × PF) / 1000
Converting VA to kW
Volt-amperes (VA) represent apparent power, while kilowatts (kW) represent real power used by electrical systems. To convert between them, you must factor in the efficiency or Power Factor (PF) of the specific AC circuit.
$$ P_{(kW)} = \frac{S_{(VA)} \times PF}{1000} $$
Real power in kW equals apparent power in VA times Power Factor divided by 1000.
