100 millitorrs equals how many inches of mercury?
That's okay...I never heard of a KEMLO!
I'm still confused, i've never heard of a TORR!
Since Torricelli invented the barometer, it is not surprising that
there is a unit of pressure named after him. One torr is equal to 1 mm
of mercury, i.e. the pressure underneath a column of mercury with a
height of 1 mm. Atmospheric pressure is about 760 mm, or equivalently,
760 torr. Good Vacuum Practice::
A more practical value is 5-10 milliTorr. Mercury was the original pumping fluid. Mercury does not break down and higher forepressures may be tolerated.

P.S.
Ooops...a bit of a mistake, I'm afraid.
The answer is .0039 inches of Hg, since 100 millitorr is 0.1 mm Hg
(not 1 mm, as I said originally).
There's a very nice conversion tool, that you can see here:
http://www.sengpielaudio.com/calculator-pressureunits.htm
Conversion of pressure or stress units
Find the millitorr box (about 1/3 of the way down the page) and enter
a value, such as 100 millitorr.
The other boxes on the page will instantly show you the conversion for
this value.
Sure enough, 100 millitorr = 0.0039370072 Inch of mercury (Hg) (32 F)
Cool, eh?
Sorry for any confusion.

fie-ga,
Thanks for your question.
According to the conversion chart available at:
http://www.highvacpumps.com/engineering/formulas.html
FORMULA & FACTORS
1 mm Hg = 100 millitorr (microns) = 10- torr
In other words, 100 milliTorrs is 1 mm of mercury.
Since 1 mm is 0.039 inches:
://www.google.com/search?sourceid=navclient&ie=UTF-8&rls=GGLD,GGLD:2005-04,GGLD:en&q=mm+in+inches
then 1 milliTorr = 0.039 inches.
Let me know if there's anything else you need on this.
