You got caught by the 2.54cms=1 inch

The best converter program I know of is the one from this site
http://joshmadison.net/software/convert/ because it's free, it's not a big program and you can use it anytime.
It tells me your CG should be 1.057023e-017 light years back from the LE
This is the greatest programme under the sun if you had to ask me, it is the first thing installed on any PC that I work on at work or at home. I do this mainly because I do all my calculations in metric, I can not understand those funny imperial units.
Cheers
