kW to kVA Reverse Convert Formula Included

Fast power conversion

Useful for generators, UPS systems, electrical loads, motors, solar systems, industrial equipment, and power planning.

Free kW to kVA Converter Tool

Calculate apparent power from real power and power factor with clean formulas and instant results.

Enter Power Values

Switch between forward and reverse calculation.
Enter real power in kilowatts.
Power factor must be between 0.01 and 1.
Choose result precision.

Conversion Result

12.50 kVA
10 kW ÷ 0.8 Power Factor
kVA = kW ÷ PF
10 kW at 0.8 power factor equals 12.50 kVA.
kW Input Unit
kVA Output Unit
0.80 Power Factor
kW ÷ PF Formula Used

Quick Examples

Power factor matters because kW is real power, while kVA is apparent power. Lower power factor means higher kVA for the same kW.

Why Use a kW to kVA Converter?

A kW to kVA converter helps size generators, UPS systems, transformers, electrical panels, and industrial equipment more accurately.

Instant Electrical Calculation

Convert kilowatts to kilovolt-amps using power factor in real time.

Reverse Conversion

Convert kVA back to kW when you already know apparent power and power factor.

Copy-Friendly Output

Copy the final result with formula details for reports, estimates, and planning notes.

What Is kW to kVA Conversion?

kW means kilowatts and represents real power. kVA means kilovolt-amps and represents apparent power. In AC electrical systems, the connection between kW and kVA depends on power factor.

The standard formula is simple: kVA = kW ÷ Power Factor. For example, 10 kW at 0.8 power factor equals 12.5 kVA.

Conversion Formula Example
kW to kVA kVA = kW ÷ PF 10 ÷ 0.8 = 12.5 kVA
kVA to kW kW = kVA × PF 12.5 × 0.8 = 10 kW

How It Works

Convert kW to kVA in three simple steps.

Enter Power Value

Type the kW value you want to convert, or switch mode to enter kVA.

Add Power Factor

Enter a power factor between 0.01 and 1. Common values are 0.8, 0.9, or 0.95.

Get Result

The tool calculates kVA or kW instantly and shows the formula used.

kW to kVA Converter FAQs

Common questions about kilowatts, kilovolt-amps, and power factor.

The formula is kVA = kW ÷ Power Factor. For example, 10 kW at 0.8 power factor equals 12.5 kVA.
kW is real power that does useful work. kVA is apparent power, which includes the effect of power factor in AC systems.
Use the actual power factor from your equipment nameplate or electrical data. If unknown, 0.8 is a common estimate for many loads.
Yes. Choose kVA to kW mode. The formula becomes kW = kVA × Power Factor.
