kW to kVAR Conversion Calculator

kW to kVAR Calculator:

Enter the real power in kilowatts (kW), enter the power factor to get the results of kVAR.

kW to kVAR Calculation

Reactive power Q_(kVAR) in kilo volt-ampere reactive is equal to the power factor times of the real power P_(kW) in kilowatts. Hence we can calculate the reactive power in kVAR formula,

kVAR = kW * tan (power angle)

Q_(kVAR) = P_(kW) * tan(φ)

If you know the power factor then,

Q_(kVAR) = P_(kW) * tan(cos^-1(pf))

Example:

Calculate the reactive power in kVAR for the 7.5 kW motor-operated 0.9pf.

kVAR = 7.5 x tan (cos^-1(pf))

= 7.5 x tan (cos^-1(0.9))

= 7.5 x tan (25.84193276)

= 7.5 x 0.4843221

= 3.6kVAR
