[Java-collab] Simple system for designating units.

[Francisco José Peñarrubia]

Maybe this links can help:

https://jsr-275.dev.java.net/
http://jscience.org/

although they seem a bit old :-(

Also, have a look to this packages:
http://www.unidata.ucar.edu/software/netcdf-java/v4.0/javadoc/index.html
http://www.unidata.ucar.edu/software/netcdf-java/v2.2.20/javadocAll/ucar/units/package-summary.html

And you may find interesting also UCUM:
http://unitsofmeasure.org/
http://www.javaworld.com/javaworld/jw-10-2007/jw-10-jsr275.html (4 
pages, very interesting).

Hope it helps.

Cheers.
