I use the astronomical unit in outreach work that I do, so this is good to be aware of.

It alters the order of the base units in defining derived units (Tables 6 and 7), it reflects the recent IAU decision to define the astronomical year as a fixed and exact number, and it makes some updates reflecting the latest CODATA, among other things. http://www.bipm.org/utils/common/pdf/si_supplement_2014.pdf Best regards, Jim Frysinger -- James R.
