You should read this guy's answer. So that you learn how to measure
viscosity in grams...

I am also attaching a copy of the answer I sent him. Please observe that I
used "inches". I intended to speak "English" to him in order to get my main
point through. It's probably hopeless anyway.

Mr. DiCorpo:
 
Thank you for your response to my inquiry.
 
I am afraid I do not understand what you mean by industry norms that specify
the abbreviation for the gram to be "gm". I would like to ask you to be so
kind to specify these sources so I can consult them. However, I know the
following national and international standards that specify the correct
usage for SI units and abbreviations:
United States: IEEE/ASTM SI 10-1997, (see attached link to USMA for some
details or go to www.ansi.org <http://www.ansi.org>  )
International: ISO 1000; SI10 (see attached link to BIPM).
 
Since my first inquiry, I did some more investigations on this system of
measurement and I became more familiar with the Stormer "viscometer". The
way this unit works it clearly measures something different than viscosity.
Personally, I believe it measures the work required to stir in a container
with defined dimensions using a paddle with a specific shape/dimensions.
 
To conclude, I stand by my initial observation and add the following:
 
1. The term viscosity or viscometer is misused as the machine does not
measure viscosity. It measures something else and I believe it is work, as
the machine resembles very much the machine that Joule used to define the
"work". If you wish, I will get more details for you regarding the Joule
experiment.
2. The gram is not a measure of viscosity. It is a measure of mass. It's
like saying that an electric motor uses 120 inches instead of 120 Volts. It
just doesn't make sense.
3. The machine does measure something that has a relation to the viscosity
of the fluid but not the viscosity of the fluid. The viscosity is a property
of a material that is clearly defined in Physics as well as it's units of
measurement. 
 
I am sure that a company like yours understands the importance of respecting
national and international standards. I also believe that you are employing
physicists, that have more understanding of the property that is measured in
this apparatus than I do. I would certainly appreciate if we could get a
better explanation of the measured properties and their relationship to the
standard units of measurement used. 
 
If your company insists in calling it a viscometer, than I need a
relationship between the displayed units and the national/intl. standards
for measuring viscosity. 
Unless you want to sell me a tape measure and call it: a voltmeter.
 
Sincerely,
 
Adrian Jadic,
Engineering/Maint. Mgr.
