### kVA to kVAR Calculator:

Enter the apparent power in kVA (kilovolt amp), power factor between 0 to 1, then press the calculate button to get the reactive power in kVAR (kilo Volt-Ampere reactive).

### kVA to kVAR calculation

Reactive power Q_{(kVAR)} in kilovolt amp reactive is equal to apparent power S_{(kVA)} in kilovolt amp times of sine of power angle (φ). Hence for converting kVA to kVAR, the formula can be written as below,

*Q _{(kVAR)} = S_{(kVA)} x sin (φ)*

Or if you know the power factor means, you can convert the formula as below,

*Q _{(kVAR)} = S_{(kVA)} x sin (cos^{-1}(pf))*

*kVAR = kVA x sin (cos ^{-1}(pf))*

__Example:__

Calculate the reactive power in kVAR of the 3.7kVA generator is operated at 0.8 pf.

kVAR = 3.7 x sin (cos^{-1}(0.8))

= 3.7 x sin (36.86989765)

= 3.7 x 0.6

= 2.2 kVAR

Hence the 3.7 kVA generator can supply 2.2 kVAR of reactive power at 0.8 pf.
