Watts to kVA calculator

Enter the power in watts (W), power factor (PF) from 0 to 1 with a 0.1 step, then press the Calculate button to get the result in kilovolt-amps (kVA).

Watts to kVA calculation

Power in watts (W)
Power factor (PF)

S(kVA) = P(W) / (1000 × PF)

The apparent power S in kilovolt-amps (kVA) is equal to the real power P in watts (W), divided by 1000, multiplied by the power factor PF.
