VA to Watts Calculator
Easily convert VA (volt-amperes) to watts using this calculator. Works for both power factor-based and pure resistive circuits. Simple, accurate, and fast.
Quick Intro: Convert VA to Watts
To convert VA to watts, simply multiply the volt-ampere value by the power factor. This essential conversion helps determine real power consumption in AC electrical systems. Use our calculator for accurate and instant results tailored to single-phase or three-phase systems.
Formulas for Watts Calculation:
Formula: Watts (W) = Volt-Amperes (VA) × Power Factor (PF)
| VA | Power Factor | Watts |
|---|---|---|
| 1000 | 0.8 | 800 |

Frequently Asked Questions - VA to Watts Calculator:
What is VA in electricity?
VA stands for volt-ampere, a unit of apparent power in an electrical circuit.
What is the formula to convert VA to watts?
Watts = VA × Power Factor.
What is a power factor?
Power factor is the ratio of real power to apparent power in a circuit, ranging from 0 to 1.
How do you calculate watts from VA and PF?
Multiply the VA value by the power factor: Watts = VA × PF.
Is VA equal to watts?
Only if the power factor is 1, which occurs in purely resistive loads.
What's the difference between VA and watts?
VA is apparent power; watts is real power actually used by a device.
Can I use this calculator for three-phase circuits?
Yes, if you account for line voltage and the correct power factor.
What if I don’t know the power factor?
Use an estimated PF (e.g., 0.8 for inductive loads) or consult equipment specifications.
Why is the power factor important in conversions?
It determines how much of the apparent power is converted into usable real power.
Does VA affect electricity bills?
Electricity bills are usually based on watts, not VA, unless you're billed for apparent power too.
