It all depends on the gain of your amplifiers and stuff.  The easiest way
to do that with the equipment you have is to just record a digital tone
with a known amplitude and then play it back to see what kind of power shows
up on the VU meter.  Then, adjust your amplitude to get 0 dB.  You just have
to make sure any level adjustments are always the same when you repeat the
technique in the future.
