### kW to VAR Calculator:

Enter the real power in kW (kiloWatts), power factor pf and then press the calculate button to get the reactive power in VAR.

### kW to VAR calculation

VAR is equal to the 1000 times of the real power P_{(kW)} in kiloWatts and the tangent of the cosine inverse of the power factor. Hence the kW to VAR conversion formula can be written as,

*Q _{(VAR) }= 1000 x P_{(kW)} * tan (cos^{-1}(pf))*

__Example:__

Calculate the reactive power in VAR of the 22kW motor is running at 0.96 pf.

VAR = 1000 x 22 x tan (cos^{-1}(0.96))

VAR = 22000 x 0.29166667

Reactive power in VAR = 6416 Volt amp reactive
