About the kVA to VA Calculator
This calculator converts kVA to VA. kVA is a thousand volt-amperes, the apparent power rating of transformers, generators and UPS units, and VA is volt-amperes, the apparent power that a supply must deliver, which is voltage times current without regard to power factor. Both are apparent power, so only the prefix changes and there is no power factor in the sum. Enter your figures and the answer appears at once, together with a few related values, and you can copy the result with one tap. The sums are done in your browser and nothing is sent anywhere.

How to use the kVA to VA Calculator
- 1Enter the value in kVA.
- 2Fill in the other boxes that the kVA to VA calculation needs, such as time, voltage or power factor.
- 3Read the answer in the large result box.
- 4Check the extra rows for related values.
- 5Press Copy result to keep it.
When you need kVA to VA
Equipment is rated in different prefixes: small adapters and UPS units in VA, transformers and generators in kVA. To compare them, one has to be converted. Multiplying kilovolt-amperes by a thousand gives volt-amperes, with no power factor involved, because both are apparent power.
Typical uses are matching a UPS to a server rack, checking that a generator covers a list of loads written in VA, and reading a rating plate that mixes both. The result also appears in megavolt-amperes for large power equipment.
How the kVA to VA sum works
VA = kVA × 1,000. A 5 kVA transformer is rated at 5 × 1,000 = 5,000 VA.
The displayed answer is rounded to six significant figures, but the sum itself is not rounded, so converting kVA to VA and back again gives you the number you started with.
- Multiply by 1,000
- No power factor is needed
- For watts use the kVA to kW tool
Mistakes to avoid when converting kVA to VA
The common mistake is to assume that kVA converts to kW the same way. It does not: kW needs the power factor. This tool only changes the prefix. For real power, use the kVA to kW calculator.
On phone and computer
On a phone, type in the boxes one after another and read the VA result underneath; the Copy button puts it on the clipboard for a message or a note. On a computer the inputs sit on the left and the answer on the right, so you can change one figure and watch the VA value move. The kVA to VA page works the same on both. When you need the opposite direction, use VA to kVA Calculator. For real power, kVA to kW Calculator takes the power factor into account, and Power Converter changes watts, kilowatts and horsepower.

Frequently asked questions
How do I convert kVA to VA?
VA = kVA × 1,000. A 5 kVA transformer is rated at 5 × 1,000 = 5,000 VA.
What is the formula for kVA to VA?
VA = kVA × 1,000. The calculator applies it exactly and rounds only the displayed answer.
What is the difference between kVA and VA?
kVA is a thousand volt-amperes, the apparent power rating of transformers, generators and UPS units. VA is volt-amperes, the apparent power that a supply must deliver, which is voltage times current without regard to power factor. They measure different things, which is why converting from kVA to VA needs more than a simple multiplication in some cases.
How many VA is 1 kVA?
1 kVA is 1,000 VA.
Is VA the same as watts?
Not exactly. VA is apparent power; watts are real power. They are equal only when the power factor is 1.
Is this kVA to VA calculator free and private?
Yes. It is free, needs no account, and runs in your browser, so the figures you type are not uploaded or stored. It is meant for planning and learning; for wiring or safety work, check the result against your equipment's rating plate and local rules.
