Apparent Power Converter

The Apparent Power Converter is a free online tool that converts between volt-amps (VA), kilovolt-amps (kVA) and megavolt-amps (MVA) in an instant. No sign-up required — enter your value, choose the unit, and get an accurate result. It's a practical reference for anyone reading equipment nameplates, sizing electrical infrastructure, or reviewing utility invoices.

What is apparent power?

Apparent power is the total power flowing in an AC electrical circuit, combining both the real power that does useful work and the reactive power stored and released by inductive or capacitive loads. It's the figure used to size transformers, generators, cables and UPS systems, which is why electricians and engineers convert between VA, kVA and MVA so often. Because apparent power accounts for both useful and non-useful current flow, it's typically higher than the real power an appliance or motor actually consumes.

How to use the Apparent Power Converter

Frequently asked questions

Is the Apparent Power Converter free?

Yes, it's completely free with no sign-up or hidden limits. Use it as many times as you need for project estimates or equipment comparisons.

What's the difference between apparent power and real power?

Real power (watts) is the power that actually performs work, while apparent power (VA) also includes reactive power. They're equal only when the power factor is 1. A low power factor means more apparent power is needed to deliver the same amount of real, usable power.

How do I convert VA to kVA?

Divide the value in VA by 1,000 to get kVA. For MVA, divide by 1,000,000. The same scaling applies in reverse when converting kVA or MVA back down to VA.

Why is apparent power used to size equipment?

Transformers and generators are rated in VA or kVA because their components must handle the total current flow, not just the useful power delivered. Undersizing equipment based on real power alone can lead to overheating or premature failure under load.
