Not only that, one of the very vocal participants in the game cant even
understand that, just because the standard way of measuring resitivity uses
a cubic centimeter, the units are NOTohms per cubic centimeter- Just for
kicks, I checked several references- (like the Handbook of Chemistry and
Physics, Marks Engineers handbook, The Van Nostrand Scientific
Encyclopedia- and the NASA spec on Units and Conversion factors- )
ALL of these think the units of Resistivity are ohm-cm, or a fraction
thereof.
The Brit checked his data after his first statement concerning the relative
resistivity (or conductivity) of Copper and Silver, and made an open (to
the list) correction- I wonder if the other guy, who used his mistake in
units as a venue for insulting comments, can be as open and say he was
wrong- ( at least, this time)
Fat chance.
