Electrical calculator
kVA to kW Converter
Convert between apparent power (kVA) and real power (kW).
About the kva to kw converter
The kVA to kW converter converts between apparent power (kVA) and real power (kW) using the power factor.
How to use this calculator
- 1
Enter power value
Enter the kVA or kW value.
- 2
Choose direction
Select kVA to kW or kW to kVA.
- 3
Enter power factor
Enter the power factor (typically 0.8 for motors, 1.0 for resistive loads).
How the calculation works
kW = kVA × PF. kVA = kW ÷ PF. Power factor is typically 0.8 for motors, 1.0 for resistive loads.
Example: 10 kVA at 0.8 PF = 8 kW. 8 kW at 0.8 PF = 10 kVA.
Safety first
These calculators provide estimates based on standard formulas and NEC guidelines. Always verify results with a licensed electrician before making installations. Electrical work can be dangerous — never work on live circuits, and always follow local building codes and regulations.
Understanding electrical units
Voltage (V) is electrical pressure, current (A) is flow rate, resistance (Ω) opposes flow, and power (W) is the rate of energy use. Ohm's law (V = I × R) relates the first three, while power formulas (P = VI, P = I²R) connect all four. Understanding these relationships is key to safe electrical design.
Important limitations
This tool provides a mathematical estimate based only on the values entered. It does not account for regulations, taxes, lender fees, market conditions, or individual circumstances.
