FFS. The dB is NOT a unit of anything. It is a ratio expressed in log
form for convenience (to avoid huge numbers). Nothing more and nothing
less.
"dB" is a ratio of powers.

"dBm", "dBV", etc., are units.
Except it's not always. * See my note to John O'Flaherty. *Not all dBs
are created equal.

I don't know why there is so much confusion in this thread.
0 dBV = 1V. It is unambiguously 1V i.e. one volt, not just "one"
That's why it has a "V" slapped on the end.
0dB = 1 - just "one"
