Dear Terry,
Thanks for the technique of doing an instant SI survey; I hadn't thought of
doing it that way.
On the issue of which is the 'correct' density unit, if asked, I would plump
for kilogram per cubic metre as it is the coherent SI unit. The unit grams
per cubic centimetre is technically a
This is a copy of a message I sent a short time ago. there is some possibility that it did not go through successfully.
Please excuse me if it is a duplication.

The signs at the Bush IAH are dual units. Only place I have
seen them in the USA.
The TEXAS DOT is going back to imperial becuase of the contractors
complaints that they do not understand metric.

I can't help feel uncomfortable using the SI prefixes with non-SI units
Recently Terry wrote (regarding average planet densities):
planet density kg/m = 7,820
planet density g/cm = 9060
etc. Surely those units should be kilograms per CUBIC metre and
grams per CUBIC centimetre. May I assume that the m and the cm
symbols were supposed to have cubed (superscript 3)
Someone posted recently an article from a newspaper in the prairie provinces arguing
against the current Canadian metric muddle and recommending going back to Imperial or
completely forward to metric. (Hard for me to see how they can go back given all the
current investment in metric, like

No. That is not a real unit. It is a search key for google. Put it into
I have additional information regarding the formation of USMA Chapters.
This is a copy of an older USMA document. I have a copy in printed form
and I have retyped it into electronic form. I'll be happy to send a
copy to anyone who is interested.
The new document is a set of suggestions of how
