But according to "Reference Data for Engineers", Capital letters are to be
used only for proper names, i.e., us is microsconds, uS is microseimens.
There is a reference to "grandfarthered" usage such as mA is milliamperes
and MA is mega-amperes. This is because mega and milli start with "m", but
the allowance goes away with everything but "m". Note that mHz and MHz and
very different, i.e., MHz is megahertz (1000 cycles per second) and mHz is
millihertz (1/1000th of a cycle per second). Note that MB won't hack it
unless "B" stands for Mr. Bell, i.e., dB (decibels).

I am afraid that the Disc Drive vendors are just going to have to deal
with the truth. If brand 1.2gb is really 0.9gb they should be exposed.
