What Is a Reactive Energy Converter?

A reactive energy converter converts between VARh, kVARh, and MVARh.

Supported Units

  • VARh — Volt-ampere reactive hours.
  • kVARh — 1000 VARh. Utility metering.
  • MVARh — 1,000,000 VARh. Large systems.

How Does Reactive Energy Converter Work?

1 kVARh = 1000 VARh. 1 MVARh = 1,000,000 VARh. Reactive energy = reactive power integrated over time.

How to Use This Tool

  1. Enter a numeric value — Type the measurement you want to convert.
  2. Select the source unit — Choose the unit you are converting from.
  3. Read the results — The tool instantly displays equivalents in every supported unit.
