There's a very good article in Wikipedia on this topic.

W = VA X P.F

Where,

W = true Power in watt (with watt meter)

VA = apparent power, the product of r.m.s volts & r.m.s amps.

P.F = power factor

and go ahead.......!!!!

The true power factor is the product of displacement power factor and distortion power factor. The below link is about true power factor.
