How to Convert Watts to Volt-Amps (VA)

The conversion between watts (W) and volt-amperes (VA) depends on the power factor (PF).

Watts to VA Calculation Formula

The apparent power S in volt-amps (VA) is equal to the real power P in watts (W), divided by the power factor PF:

S(VA) = P(W) / PF

So volt-amps are equal to watts divided by the power factor:

VA = W / PF

Example Calculation

If you have a power measurement of 100 watts and a power factor of 0.8, the calculation would be:

S(VA) = 100 W / 0.8 = 125 VA

Understand the Conversion

The relationship between watts and volt-amps is crucial in electrical systems. The power factor indicates how effectively the current is being converted into useful work output. A power factor of 1 means all the power is being effectively converted, while lower values indicate less efficiency.
