Golly Brenda how does
210VA = 95.55W
850VA = 386.75W

wikipedia on volt-ampere
A volt-ampere in electrical terms, means the amount of apparent power in
an alternating current circuit equal to a current of one ampere at an emf
of one volt. It is equivalent to watts for non-reactive circuits.

Are you using peak, rms, or average factors?

I assume the VA figures given by John are rms values

The calculator used assumes a power factor of .70. It is right in line with
the calculations used for USP'es in their V/A to W conversions.
