Apparent Power Converter

By Suraj GiriUpdated 24 September 2026

This page converts an apparent power from one unit into another. Every value passes through the volt-ampere, the SI unit apparent power is held in, and apparent power stays apparent power: a unit only converts inside its own dimension.

How do you convert apparent power between VA, kVA and MVA?

Pick the unit you have, pick the unit you want, and type the value. The page multiplies by the factor between the two and prints the arithmetic under the result, so the answer and the working are the same object.

1. Choose the unit your value is in. This page opens on the kilovolt-ampere.
2. Choose the unit you want it in. This page opens on the megavolt-ampere.
3. Type the value, or the value with its units, such as 750 kVA to MVA. The result and the factor behind it appear together.
4. Read the working. It converts into the volt-ampere first and out again, which is the same two lines you would write by hand.

VA, kVA and MVA measure apparent power, so for reactive power in VAR, or the current or voltage behind the rating, go to the electrical units converter.

One row per unit this page offers, each measured against the volt-ampere. The last column says whether the factor is a definition or a reading of one.

Where These Factors Come From

Every factor above is read from the knowledge base rather than typed for the page, and every result is worked from those factors. These are the statements it holds for apparent power.

• Apparent power is RMS voltage times RMS current, measured in volt-amperes. Real power in watts is apparent power times the power factor, so a 1 kVA supply at a power factor of 0.8 delivers 800 W.
• An SI prefix multiplies a unit by a power of ten: k is 10^3, M is 10^6, G is 10^9, m is 10^-3, micro is 10^-6 and n is 10^-9. The prefix belongs to the unit, so 1 kV is 1000 V.
• Reactive power is measured in volt-amperes reactive. Real power P, reactive power Q and apparent power S are related by S^2 = P^2 + Q^2, which is why three unit names exist for one dimension.
• How this page reports a result result in the target VA prefix, plain decimal; no power factor is applied

What Does Power Factor Change?

Power factor is the ratio of real power to apparent power, and it decides how much of a supply rated in volt-amperes turns into watts. This page scales a value that is already in volt-amperes; it applies no power factor and produces no watts.

• Kilovolt-amperes are not kilowatts. The power factor links the two, and this page applies none.

The rule behind this factor is the same for every unit - the prefix ladder from micro to mega.
