### W to VAR Calculator:

Enter the real power in Watts and the power factor to get the reactive power in VAR (Volt-Amp Reactive).

### W to VAR Calculation:

Watt is the unit of real power and VAR is the unit of reactive power. Reactive power in Volt-Amp Reactive Q_{(VAR)} is equal to the tangent of power angle times of the real power P_{(W)} in Watts. Hence the formula can be written as,

*Reactive power in VAR Q _{(VAR)} = P_{(W)} x tan(φ).*

Here power angle (φ) is equal to the cosine inverse of the power factor.

__Example:__

Calculate the reactive power consumption of the 200 Watt motor is operated at 0.9 pf.

*Reactive power in VAR = 200 x tan (cos ^{-1(}0.9))*

*Q _{(VAR)} = 200 x 0.4843221*

*= 96.8 VAR.*
