[comp.text] Inverted Characters in [di]troff

bruno@sdcc10.ucsd.edu (Bruce W. Mohler) (03/07/91)

I'm taking an electronics class and use ditroff to format the
tables of formulas that I need.  When we got to Ohms (this is
a first semester electronics class), I just used \(*W to produce
the (upper-case) omega (ohm symbol).  When we got to conductance,
the teacher said that the symbol for this was called am Mho
("ohm spelled backwards") and that the symbol was an inverted
ohm (Omega).  Is there any way to produce this symbol using
troff?

(I'm using DWB 3? without output to tps/tpscript to a NEC 890
PostScript printer.)

Thanks, in advance.

Bruce

Your teacher is out of date. The SI unit for conductance is siemens
(sing. and pl.). The symbol is S.
