How it works
- Enter a reactive power value and its unit.
- The value converts to every other reactive power unit at once.
- Read off the result you need.
VAR, kVAR, and MVAR are related by powers of a thousand — this converter multiplies or divides by 1,000 to move between them, the same relationship as watts, kilowatts, and megawatts.
FAQ
Is my data uploaded anywhere?
No. Conversion happens entirely in your browser — nothing is sent to a server.
What units are supported?
VAR, kVAR, and MVAR (volt-amperes reactive, and their kilo/mega multiples) all convert to each other.
What is reactive power used for?
It measures the non-working power in an AC circuit caused by inductive or capacitive loads — used in electrical engineering for power factor correction and grid capacity planning.
How is reactive power different from real power?
Real power (watts) does actual work; reactive power (VAR) oscillates between source and load without being consumed, but still needs to be supplied by the system.
