No it is not.
VA * PF = W for VA = volt amps, PF = power factor, W = watts (or true power)
PF = the cos of the phase angle between the current and the voltage
(assuming both are sine waves)
Peak Volts * 0.707 = RMS volts, again for sine waves only.

Converting VA to W is same as converting peak V to RMS V.
