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

VA to watts conversion formula

P=The real power P in watts (W)
S=the apparent power S in volt-amps (VA)
PF=the power factor PF

P(in Watts) =  S(VA) × Power Factor

So that you can define power p in watts are equal to VA times the PF.

watts = volt-amps(VA) × Power Factor
or
W = VA × PF

Let's take an example
Example#1
Find out the power P in circuit where S=the apparent power is 2000 VA,PF=the power factor is 0.8
Apply formula for the Solution:
P = 2000VA × 0.8 = 2500W
