Re: LightYear Conversion is Incorrect in Units Package


The plot thickens...it seems that Mathematica uses a year of 365.24219 days
or so, but the National Institute of Science and Technology says (see
http://physics.nist.gov/Pubs/SP811/contents.html page 64 of the pdf or you
can find it at http://physics.nist.gov/Pubs/SP811/appenB8.html ) mandates
that for this purpose, a year is 365.25 days, which makes a light year
9.4607*^15*Meter, which is different from what Mathematica says. So it is a
bug!
