Formula & Calculation Steps:
kVA = Watts / (1000 × PF)
Converting Watts to kVA
Real power measured in Watts (W) can be converted to apparent power in kilovolt-amps (kVA) using the circuit's Power Factor (PF). This conversion is heavily used when sizing generators or transformers that are rated in kVA.
$$ S_{(kVA)} = \frac{P_{(W)}}{1000 \times PF} $$
Apparent power in kVA is Real Power in Watts divided by (1000 times Power Factor).
