mHz is the abbreviation for millihertz. This is subaudible. It is a pet
peeve of mine that people use abbreviations incorrectly, especially when
they involve misleading units. I see people that say that they need
something to tune so many mHz when in fact they really mean that they want
something to tune so many MHz. They are going to be very surprised when
they get what they asked for rather than what they meant.
All goes back to mean what you say or say what you mean.
Mega is 10^6, milli is 10^-3. A difference of 10^9. See
<http://physics.nist.gov/cuu/Units/prefixes.html> for the definitions of SI
units.
Wish we would go back to Megacycles. A self defining term.
