Power Factor Calculator
Calculate Power Factor (PF), Phase Angle, and Apparent Power (kVA) from Real Power (kW) and Current.
Electrical Measurements
Power Factor
0.80
PF
Efficiency Percentage:
80.0%
Reactive Power (kVAR):
60.0 kVAR
Phase Angle (θ):
36.87°
PF = 80 kW ÷ 100 kVA = 0.80
What is Power Factor?
Power Factor is the ratio between Real Power (kW) and Apparent Power (kVA). A higher power factor means your electrical system uses power more efficiently.
