Hi:

	Almost.  See my later post for an explanation of what triggered that
outburst.  I just remembered something about "metric" usage, and least
in one Japanese industry.  A number of years ago I was involved in
studying the feasibility of putting a radar system in a Mitsubishi MU-2
corporate plane.  (The location was San Angelo, Texas, a rather strange
place for a Japanese aircraft company to be doing business.)  Their
dimension system worked in millimeters, with some of the dimensions as
high as 25000!  They sent me a bunch of drawings in japanese, which one
of the local Japanese engineers tried to translate.  Seems a lot of
their names for airplane parts were originally english, then
transliterated into japanese.  One example:  Kikiyu came in and asked
"is this an airplane or a boat?".  The two "bulges" for the landing gear
came out to something in japanese which transliterated back into
"barges".  No problem with understanding the stuff, of course.

	On the subject of millihertz, I haven't seen the term used in EE
circles, but in the design of pneumatic control systems for large plant
control systems the expression of frequency in "radians per hour" seems
relatively common.  Compared to what we do, that stuff is SLOW!
