VA = Watts / PF
Converting Watts to VA
In AC circuits, real power (Watts) and apparent power (VA) are often different due to reactive loads like motors. To find VA from Watts, you must divide the real power by the Power Factor (PF).
$$ S_{(VA)} = \frac{P_{(W)}}{PF} $$
Apparent power in VA is Real Power in Watts divided by Power Factor.
