How to convert VA to watts

How to convert apparent power in volt-amps (VA) to real power in watts (W).

VA to watts calculation formula

The real power P in watts (W) is equal to the apparent power S in volt-amps (VA), times the power factor PF:

P(W)S(VA) × PF

So watts are equal to volt-amps times the power factor.

watts = volt-amps × PF

or

W = VA × PF

Example

What is the real power in watts when the apparent power is 3000 VA and the power factor is 0.8?

Solution:

P = 3000VA × 0.8 = 2400W
