kVA to kW Calculator
Real power in kilowatts:
Calculation Formula
P(kW) = S(kVA) × PF
Where:
- P(kW) is the real power in kilowatts
- S(kVA) is the apparent power in kilovolt-amps
- PF is the power factor (a dimensionless number between 0 and 1)
How to Convert kVA to kW
To convert from kilovolt-amps (kVA) to kilowatts (kW), you need to know the power factor (PF) of the electrical system.
The real power P in kilowatts (kW) is equal to the apparent power S in kilovolt-amps (kVA), multiplied by the power factor PF:
Example Calculation
What is the real power in kilowatts when the apparent power is 5 kVA and the power factor is 0.8?
P = 5kVA × 0.8 = 4kW
