Consider: http://www.ideafinder.com/history/inventors/hertz.htm or,

or, http://tf.nist.gov/timefreq/general/glossary.htm (click on "M" or
"J-K" - these folks should know the difference)

I have a different understanding. Hz is written with a capital H not to
pay homage to Mr. Heinrich Hertz, but more simply because all
measurement units begin with a capital letter.

That contradicts units like the gram (g, kg, mg), the meter (m, cm, mm,
km) the liter/litre (l, ml), the second (sec, msec)... or at least how
they are presented in all my science texts, and...

Homage was instead paid to Mr Kelvin when they decided that the capital
K is assigned to the temperature measurement unit (kelvin degree)
instead than to the 1000 multiplier.

....Fahrenheit (F), Rankin (R), Henry (H, mH), Farad (F, pF, nF), Volta
(V), Ampere (A), Gauss (G, mG), Tesla (T), Watt (W, mW, kW, MW)...

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),

Am I missing your sarcasm?

Although, I frequently (almost always) see 'million' prefixed by 'm' by
the news media in headlines, like 'XYZ Liable for $10m' A liability of
ten cents isn't a big news item. In my opinion.
