+1 for VolumetricMassDensity
If there is confusion on the meaning of this unit, then I think it is worth a
few extra characters to make the usage clear.

Dear all,
Using a similar method as Alex to find terms for JSR 375, such "Doodle like"
approach means, we so far got
MassDensity: 4
Density:2
Those who haven't voted yet, please do either here or in JIRA (where I also
did for completeness)
Chose from either of these:
* Density
* MassDensity
* VolumetricDensity (meaning no change)
* VolumetricMassDensity
Alphabetically ranked, the order does not mean any preference.
Feel free to list say 2 favorites in your order. They'll both be counted. If
we got a close tie, then ranking 2nd choices as 1/2 instead of 1 might help.
That currently still left MassDensity: 3 and Density: 2.
Thanks,
Werner

Martin/all,
Thanks for your vote. Except for this table which is a little tricky because
it says "Examples" the other two are exactly identical in the NIST site.
The only system specific to the US isn't even SI, so they all quote the same
common source. As there are at least two other *Density quantities in that
table of examples I would not simply call it Density. Wikipedia quotes the
full term "Volumetric Mass Density", whether it used a French description or
not, I can't say. Wikipedia is always as good or bad as the people
contributing.
I'd prefer
MassDensity
To avoid confusion with others, regardless if we include them in the API or
not.

Hello Werner
I think we should keep in mind in the specification that the international
reference for units of measurement is BIPM rather than NIST. In my
understanding, NIST is specific to one country (USA), while BIPM defines the
international standard.
BIMP lists some derived units there:
http://www.bipm.org/en/publications/si-brochure/section2-2.html
For the density, both "density" and "mass density" are listed by BIPM as
acceptable terms. Interestingly, the French translation is "masse volumique".
Maybe the English "Volumetric density" is derived from that French
translation.
I wonder, isn't the plain "density" word widely understood as "mass density"?
Is the risk of confusion really high?
My vote would be:
1. (my preference) Density
2. (second choice) Mass density
I would like to avoid the other choices since they are not listed by BIPM.

Dear Experts,
Sorry to bother you with this one again. Since it is just a single choice,
maybe we can close it sooner, so the quantity scope tasks can be finished
soon, too.
https://java.net/jira/browse/UNITSOFMEASUREMENT-9
Asks for either
1. MassDensity
1. VolumetricDensity
1. VolumetricMassDensity
Please advise with a +1 vote either in this thread or directly with the JIRA
ticket.
As discussed with Leo last weekend, there are a few manual steps required on
the ME side, so having the API and all types it contains frozen soon would be
beneficial for these steps, too.
I am not particularly biased. Having places like NIST and other standard
bodies just calling it "Mass Density" is probably a good argument. As
Wikipedia explains
http://en.wikipedia.org/wiki/Density the proper full name
is "Volumetric Mass Density", so the name we had so far is one (maybe a
lesser used) short form. Either we keep it, use the more common one or the
full name.
Thanks,
Werner
