Whoa there LT! Most meters measure RMS. You'd better know p-p to rate
your caps. 

P=1.414*RMS
P=.5*P-P
P-P=2*P
RMS=.707*P

VA Ratings (or Volt-Ampere ratings) refer to power capabilities.
Power=Volts*Amps

RMS stands for "Root Mean Square"  to find it, take your peak to peak
voltage and multiply by .707. or take RMS voltage and divide by .707 to
get
back to the VP-P that most meters measure.

Hope I helped.
