Power Factor Calculation

This web page can be used to calculate the power factor of a load. Table 1 should be used when the power factor angle is known (also referenced as the impedance angle or the angle between the voltage and current). Table 2 should be used when the Real Power (KW) and the total power (also referenced as complex power with the units of KVA) are known.
