Something to add to the list:
MHz Mega Hertz
mHz milli Hertz
These are often used interchangeably, where in some cases it is obvious
what is meant, in other case you are left guessing.
The SI system works well when properly used.
You see someone stating that they are on 432.00 mHz when they really
mean 432.00 MHz.
A very big difference.
