Power factor calculation for metering application

I have been using the metering library on KM14Z board. Currently I am facing problem in calculating the power factor using the Filter based algorithm of metering library. There are no API's available to calculate the power factor, therefore I am calculating it by dividing Active power with S(VA).

PF = P(Watts)/S(VA).


This calculation gives me wrong results. Could someone guide me on this issue.


Thanks in advance.
