### Watts to kVAR Calculator:

Enter the real power in watts, Power factor (0 to 1) and then press the calculate button to get the reactive power in kVAR.

### W to kVAR calculation:

kVAR is the unit of reactive power in kilo rating. Hence, the reactive power Q_{(kVAR)} is equal to the real power P_{(W)} in watts times of the tan of cos^{-1} of the power factor divided by 1000. Therefore calculating W to kVAR,

*Reactive power in kVAR = P _{(W)} x tan (cos^{-1}(pf))/ (1000)*

*kVAR = W x tan (cos ^{-1}(pf)) / 1000*

__Example:__

Calculate the reactive power in kVAR of the 500 Watts motor operated at 0.86pf.

kVAR = 500 x tan (cos^{-1}(0.86)) / 1000

Reactive power = 500 x 0.59336515 /1000 = 0.296 kVAR
