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

"dB" is a ratio of powers.

dB is a ratio.

dBft and dBlb to talk about decibels with respect to a foot or a pound

Probably the most common measurement, dBSPL, is actually referenced to a
pressure.
