Hi Jim:
But what you show violates the SI rules, even though it's the correct
calculation.

I don't understand what is wrong with 'Hz'.
As Time in seconds is a SI unit, Frequency is the reciprocal value of
time, f=1/T, Frequency is not a SI base unit but a SI coherent derived
unit (in the list with special names and symbols as force, pressure,
charge, power, resistance etc.). [11th CGPM,
Hi Arnold:
The web site contains a lot of unit related computations, see:
http://futureboy.us/fsp/frink.fsp
and it's author has spent quite a lot of time in understanding units.
In school when I learned this it was called dimensional analysis.
Here is the section dealing with Hertz:

For me it looks like this guy hates SI system. There are many out there.
How cares?
The problems arise if systems get mixed up and at least one end of the
communication link thinks the other does the same.

I don't think that SI is the last system we see and that is for the
decimal system too.

But to think the american system is better must be a joke. Even the

That's historical. All of the original prefixes (from 1795) were lower
case. When new ones extended the magnitudes (in 1960), capitalization
was necessary to distinguish M(ega) from m(icro). They
