 [EMAIL PROTECTED], you make a good point, and e-gold will
 refine that conversion factor to make it more accurate. send
 me your e-gold account number for a reward bounty.

Thank you thank you!  You can credit it to 105440, please, if you
don't mind supporting America's most aggressive defender of firearms
ownership.  It's tax deductible, too.

 from a scientific basis, i opine that the most precise
 and accurate conversion factor between ounces and
 grams to be exactly:
 which is derived from the NIST data stating that:
 1 grain = 64.79891 milligrams (*exactly* because bold font)
 (see http://physics.nist.gov/Pubs/SP811/appenB9.html)
 also a troy ounce is *exactly* 480 grains, so we arrive at
 64.79891 mg / grain * 480 grain / troy ounce * 1/1000 g/mg = 
 31.1034768 grams per troy ounce
 (for some independent form of verification, i find this number
 in several web based troy ounce - gram conversion tables)

Interesting.  Oh well, either 31.1034768 or 31.103477 is better than
31.103.  Probalby my calculator was chopping off digits.

 e-gold account balances are tracked by weight to 6 decimal
 places - in troy ounces. lets see what a difference the conversion
 factor might make. a spend can only occur to a precision of
 6 decimal places in ounces. for a spend denominated in grams,
 can a conversion factor of 31.103 vary the weight amount when
 performed in ounces to 6 places...

Right, the actual practical difference is very very small, but it is a
systemic bias, which is bad, even if it is small.  e-gold has over a
ton in circulation, so being off by even one part in 100,000 does add
up to something real.

Thanks for fixing this!

A bold statement!

What does e-gold say?

e-gold is using the wrong gram-ounce conversion.  The correct unit is
one troy ounce = 31.103477 grams, exactly, not 31.103, which is what
e-gold currently uses.  I can document the source of the 31.103477 if
you care,

Yes, document it thoroughly please.

but it is the correct value; any other value is wrong,
according to generally acknowledged standards bodies.  Please fix
this.  It makes a difference for those of us who are trying to
interface with e-gold and keep our accounts in grams, not ounces.

Please fix it!  Thank you
