kVA to kW Converter
Convert apparent power (kVA) to real power (kW). This conversion requires knowing the power factor of the electrical load.

Kilovolt-Ampere ↔ Kilowatt
kVA
kW
Calculation Formula
100 kVA × 0.8 PF = 80 kW
Worked Example
Convert 100 kVA to kW with a Power Factor of 0.8:
100 kVA × 0.8 = 80 kW

Note: Voltage is not required to convert between kVA and kW, only the power factor.
| kVA | kW (PF=0.8) | kW (PF=0.9) | kW (PF=1.0) |
|---|---|---|---|
| 10 kVA | 8 kW | 9 kW | 10 kW |
| 25 kVA | 20 kW | 22.5 kW | 25 kW |
| 50 kVA | 40 kW | 45 kW | 50 kW |
| 100 kVA | 80 kW | 90 kW | 100 kW |
| 250 kVA | 200 kW | 225 kW | 250 kW |
| 500 kVA | 400 kW | 450 kW | 500 kW |
Understanding the Conversion
kVA (kilovolt-amps) is apparent power (total power in the system), while kW is real power (power that does actual work). Multiplying kVA by the power factor (a number between 0 and 1) gives the kW.
