Some AC Voltage Conversion:
Peak to rms: multiply peak by 0.707. Peak to average: multiply peak by 0.637. Rms to peak: multiply rms by 1.414. Rms to average: multiply rms by 0.9. Average to rms: multiply avg by 1.111. Average to peak: multiply avg by 1.567.
Mostly voltmeter shows rms value. So, Vav = 0.9*Vrms = 0.9*500. = 450mV ~ [D] 451 mV.
