I was referring to all the measurement units that bear the name of a scientist.
Those units all begin with a capital letter

fermi = fm (yeah, I know, a non-SI unit, but nuclear physicists never
talk about femtometers, they talk about fermis... and it just so
happens that a fermi is a femtometer.)

This explains why kilohertz is written with a small k, an exception to the
general rule that all multipliers have a capital lettere *(kHz, MHz, GHz,
THz).

...deci (d), centi (c), milli (m), nano (n), pico (p), femto (f), atto (a),

The ones you mention are not multipliers (i.e. 1,000, 1,000,000, etc,) but
sub-multipliers (i.e. 0.001, 0.000001, etc) . The general rule is that
multipliers have a capital letter, the sub-multipliers have a small letter

General rule, but there's other exceptions too: h (hecto) for 100, da
(deca) for 10. In fact the multipliers for 10, 100, and 1000 all use
lowercase letters - how's that for another general rule for ya!

Am I missing your sarcasm?

You must have missed it, because I am always quite serious and never sarcastic.

It's a little bombastic to come across setting up all sorts of rules
and then have those who work in industries point out all the
exceptions.
