The kVA to Kilowatts Calculator is a useful tool for converting apparent power in kilovolt-amperes (kVA) to real power in kilowatts (kW). This conversion is essential for understanding the actual power consumption or generation capacity of electrical systems. By inputting the kVA and the power factor (PF), users can quickly determine the equivalent power in kilowatts, providing valuable insights for various electrical applications.
Formula of kVA to Kilowatts Calculator
To perform the conversion, the calculator uses the following formula:
Where:
- kW is the power in kilowatts.
- kVA is the apparent power in kilovolt-amperes.
- PF is the power factor, a dimensionless quantity typically between 0 and 1.
The power factor indicates the ratio of real power (kW) to apparent power (kVA). The formula to calculate the power factor is:
PF = kW / sqrt(kW^2 + kVAR^2)
Where:
- PF is the power factor.
- kW is the real power in kilowatts.
- kVAR is the reactive power in kilovolt-amperes reactive (kVAR).

Example of kVA to Kilowatts Calculator
Let's consider an example to understand how the kVA to Kilowatts Calculator works in practice:
Suppose we have an electrical system with an apparent power of 100 kVA and a reactive power of 80 kVAR. Using the calculator, we can determine the real power (kW) and the power factor (PF).
- Input:
- kVA = 100
- kVAR = 80
- Calculation:
- Using the formula for power factor: PF = 100 / sqrt(100^2 + 80^2) ≈ 0.6
- Using the formula for real power: kW = 100 × 0.6 = 60 kW
- Output:
- The electrical system has a real power of 60 kW and a power factor of 0.6.
