power factor is measured in degrees of angle. Its the angle between real and apparent power.
power factor = real power/apparent power=Watt/VA=theta degrees.
It gives the information of how much lag is in between AC line current to voltage. In real world, the electrical equipment uses R, L, C and other active components as well like diodes, transistors, switching circuits. These circuits induce harmonic noise to 50Hz line frequency. Hence, the actual power factor is one calculated above plus the total harmonic distortion.
refer AN1106 application note on power factor from www.microchip.com. This is very comprehensive enough to understand power factor and its correction.
Hope this helps!
