How to Convert Volt-Amperes (VA) to Watts
To convert volt-amperes (VA) to watts (W), you need to know the power factor (PF), which is the ratio of real power (watts) to apparent power (volt-amperes). The formula is:
VA to Watts Calculation Formula
The real power P in watts (W) is equal to the apparent power S in volt-amperes (VA), multiplied by the power factor PF:
P(W) = S(VA) × PFThus, watts are equal to volt-amperes multiplied by the power factor:
W = VA × PFExample Calculation
If you have an apparent power measurement of 100 VA and a power factor of 0.9, the calculation would be:
P(W) = 100 VA × 0.9 = 90 WFor more information visit the Volt-Amperes.
VA to Watts Conversion Table
Formula: W = VA × Power Factor (PF)
