Your electric meter measures watts, not VA. If you know the power
factor, you can convert these VA measurements to watts and eventually

watts (as well as PF).

My understanding was that the watt-hour meter actually measure VA-hours. I
asked the electric company once, and that said that was the case. But I
wasn't speaking with an engineer.


That's VARs, not VA-hours. For 'volt-ampere reactive'.
