Lots of confusion abt how the dB standard has been applied and used over the

I remember someone asking me what mmfd was. He had a very old schematic
diagram.
I said "it is milli-milli-femto-deci and when it gets that small the units
really don't matter".

All the computer ads have millihertz CPUs (mhz)

I get prescriptions from the drug store that have so many MG dosage printed
on the label.

OOPS now I am on a roll.
You know that there were no DB9 connectors until the Computer
community started calling DE9 connectors DB9. Then distributors had to
change the name in
their catalogs to accommodate the computer guys and ultimately the
manufacturers had to do the same.
