Convert kilowatts (kW) to volt-amps (VA) with our easy calculator. Input power and power factor to get accurate VA for electrical systems.
The kW to VA Calculator is a simple tool that helps you convert real power (kilowatts) to apparent power (volt-amps). In electrical systems, especially in AC circuits, the difference between real power (kW) and apparent power (VA) becomes important when power factor is involved. This calculator requires just two inputs – the power in kilowatts and the power factor (usually between 0 and 1). It’s useful for engineers, electricians, and solar or generator sizing applications where precise VA ratings are necessary. Whether you're working with motors, transformers, or inverters, this tool provides a fast and accurate conversion of kW to VA.
VA = kW × 1000 ÷ Power Factor
Where:
Convert kilowatts (kW) to volt-amps (VA) quickly with this accurate calculator. Enter power in kW and power factor to calculate total apparent power in VA easily.
| Power (kW) | Power Factor | Apparent Power (VA) |
|---|---|---|
| 1 | 1.0 | 1,000 |
| 1 | 0.8 | 1,250 |
| 2.5 | 0.9 | 2,778 |
| 5 | 0.85 | 5,882 |
Multiply kilowatts by 1000, then divide by the power factor. VA = kW × 1000 ÷ PF.
Most residential and commercial loads have a power factor between 0.8 and 1.0.
Yes, unless the power factor is 1, VA is always greater than or equal to kW.
kW is real power; VA is apparent power. VA includes both real and reactive power.
Yes, the conversion depends on the power factor of the load.
Yes, but ensure the total kW and power factor represent all phases.
Lower power factor increases VA, meaning larger equipment is needed.
Use an estimated value like 0.85 for general-purpose calculations.
Yes, generator sizing is based on VA, not just kW.
You may undersize or oversize your system, leading to inefficiency or failure.
