VA to Watts Calculation

Real Power
0.8W
Σ

Calculation Formula

P(W) = S(VA) × PF

To calculate real power in Watts, multiply several volt-amps by the power factor (typically 0.8 for complex loads).

Typical Reference Values

Ideal Resistive
1000 VA @ 1.0 PF = 1000 W
Standard Computer
500 VA @ 0.7 PF = 350 W
Motor Load
2000 VA @ 0.8 PF = 1600 W
Inductive Load
1500 VA @ 0.6 PF = 900 W

Understanding this conversion

Convert Apparent Power (VA) to Real Power (Watts) by accounting for the power factor phase lead or lag.
