How to convert kVA to Watts

kVA to watts calculation formula

P(W) =  1000 × S(kVA) × PF

The real power P in watts (W) is equal to 1000, multiplied by the apparent power S in kilovolt-amps (kVA), multiplied by the power factor PF.


W = 1000 x kVA x PF
watts = 1000 x kilovolt-amps x PF

For example:

Power (S) = 2,5kVA
PF = 0,7

Power (P) = 1000 x 2,5kVA x 0,7 = 1750W
