VA to kW Calculator
Use our free VA to kW calculator to convert volt-amps to kilowatts (kW) accurately. Supports single and three-phase power systems with formula & examples.
Quick Intro: Convert VA to KW
The VA to kW Calculator helps you convert apparent power (volt-amperes) into real power (kilowatts). To get an accurate result, the calculation takes into account the power factor and system type (single or three-phase). This is critical for sizing electrical equipment and optimizing load efficiency.
Formula to Convert VA to KW
- Single Phase:
kW = (VA × PF) ÷ 1000 - Three Phase:
kW = (VA × PF × √3) ÷ 1000
VA to KW Calculator Overview

Sample VA to KW Canversion Table
| VA | PF | kW (Single Phase) | kW (Three Phase) |
|---|---|---|---|
| 1000 | 0.8 | 0.8 | 1.39 |
| 5000 | 0.9 | 4.5 | 7.79 |
Frequently Asked Questions - VA to kW Calculator:
How do I convert VA to kW?
Use the formula: kW = (VA × Power Factor) ÷ 1000.
What is the power factor?
Power factor is the ratio of real power to apparent power, usually between 0.7 and 1.
Is power factor important for VA to kW conversion?
Yes, it directly affects the kW result from VA.
What is VA?
VA (volt-ampere) is the unit of apparent power in AC systems.
Can I convert VA to kW without PF?
No, power factor is necessary for accurate conversion.
How do I convert VA to kW for 3-phase systems?
Use the formula: kW = (VA × PF × √3) ÷ 1000.
What is kW?
kW stands for kilowatt, a unit of real power.
Can I use this for DC circuits?
For DC, VA = W, so no PF is needed; divide by 1000 to get kW.
Why is VA greater than kW?
Because VA includes both real and reactive power, not just real power.
Is this calculator suitable for industrial use?
Yes, it's accurate and supports both single and three-phase loads.
