Kilowatts (kW) to Kilovolt-amps (kVA) Calculator
Apparent power in kilovolt-amps:
Calculation Formula
S(kVA) = P(kW) / PF
Where:
- S(kVA) is the apparent power in kilovolt-amps
- P(kW) is the real power in kilowatts
- PF is the power factor (a dimensionless number between 0 and 1)
How to Convert kW to kVA
To convert from kilowatts (kW) to kilovolt-amps (kVA), you need to know the power factor (PF) of the electrical system.
The apparent power S in kilovolt-amps (kVA) is equal to the real power P in kilowatts (kW), divided by the power factor PF:
Example Calculation
What is the apparent power in kilovolt-amps when the real power is 5 kW and the power factor is 0.8?
S = 5kW / 0.8 = 6.25kVA
