Re: power factor correction is Fact .. Not Fiction The author of that article needs to go and get the FACTS. Residential customer meters measure kWh not kVAh. »en.wikipedia.org/wiki/Electricity_meter The author says 'We can easily check this for ourselves: Go outside to where your billing meter is, and look at the dial: It reads in “Volt-Amperes”.' If he had looked at a residential meter for himself maybe he would not have made such a big mistake. |

Brooklyn, NY | You do know that
W(Watt)=V(volt)*A(Amps)
so substitute W with VA is perfectly fine. |

| said by Gres7:You do know that W(Watt)=V(volt)*A(Amps) so substitute W with VA is perfectly fine. You do realize that the entire point of this thread is taking into account power factor correction. Watts only equal V-A when the power factor is 1 (e.g. incandescent lighting). When the power factor is not equal to 1, you need to divide the Watt rating by the power factor to get the V-A rating.
