Calculate power factor from real and apparent power.

Reset

Formula

PF = PkW / SkVA

Variables

  • P — real power
  • S — apparent power

Worked Example

Input: 8 kW, 10 kVA

Result: PF = 0.8

Assumptions & Notes

Valid range 0 ≤ PF ≤ 1 for passive loads. True PF may differ from displacement PF with harmonics.
