Power factor is the ratio of working power to apparent power. It measures how effectively electrical power is being used. To determine power factor (PF), divide working power (kW) by apparent power (kVA). In a linear or sinusoidal system, the result is also referred to as the cosine θ. PF = kW / kVA = cosine θ kVA.
