Reactive Energy Converter
- 4500 x 1000 4500000 volt-ampere-hour reactive
- 4500000 / 1000000 4.5 megavolt-ampere-hour reactive
This page converts a reactive energy from one unit into another. Every value passes through the volt-ampere-hour reactive, the SI unit reactive energy is held in, and reactive energy stays reactive energy: a unit only converts inside its own dimension.
How do you convert reactive energy between VARh, kVARh and MVARh?
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.
- Choose the unit your value is in. This page opens on the kilovolt-ampere-hour reactive.
- Choose the unit you want it in. This page opens on the megavolt-ampere-hour reactive.
- Type the value. The result and the factor behind it appear together.
- Read the working. It converts into the volt-ampere-hour reactive first and out again, which is the same two lines you would write by hand.
Reactive Energy Conversion Table
One row per unit this page offers, each measured against the volt-ampere-hour reactive. The last column says whether the factor is a definition or a reading of one.
| Unit | Symbol | In the SI unit | Exact? |
|---|---|---|---|
| volt-ampere-hour reactive | VARh | 1 | exact |
| kilovolt-ampere-hour reactive | kVARh | 1000 | exact |
| megavolt-ampere-hour reactive | MVARh | 1000000 | exact |
Worked Examples
The question the bank ranked highest for this page, answered with the working.
What is 4500 kVARh in MVARh?
- 4500 x 1000 4500000 volt-ampere-hour reactive
- 4500000 / 1000000 4.5 megavolt-ampere-hour reactive
4500 kVARh = 4.5 MVARh
Where These Factors Come From
Every number above is read from the knowledge base rather than computed for the page. These are the statements it holds for reactive energy.
- Reactive energy is reactive power times time, metered in volt-ampere-hours reactive. One kVARh is 1000 VARh, the same prefix step as one kWh over one Wh.
- 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.
- How this page reports a result result in the target VARh prefix, plain decimal

What Does a VARh Meter Record?
A reactive energy meter measures reactive power held over time, in the same way a kilowatt-hour meter measures real power over time. It is read separately on an industrial supply, and the two readings are never added together.
The rule behind this factor is the same for every unit - how SI prefixes scale a unit.
Frequently Asked Questions
What is reactive energy?
Reactive power held over a length of time, in the same way real energy is real power held over time. It is measured in volt-ampere-hours reactive and is metered on its own.
Why do industrial bills meter kVARh as well as kWh?
Reactive energy still loads the cables and transformers that carry it, even though it does no work. Metering it separately lets a supplier charge for that load rather than hiding it inside the real energy figure.
How many VARh are in a kVARh?
1000 VARh.
