OdBm ref 600 Ohm is 775mV rms, but 0dBm ref 50 Ohm is something like
120mV. That's why it's often easier to use dBV.

Agreed. And 0dDm ref 600 ohm (775mV) is dBu, if memory serves, so adding
to the confusion!

It's why I left off any suffix letter. If the OP is really interested in
all the options, a quick search will give reading matter for a few months.
And probably leave him even more confused than me. ;-)

It is vanish itself. About somewhere around the acoustic power of a

Or the square root of f*** all....

If 0(f*** all)1, then sqrt(f*** all) (f*** all).

Oh dear.
