Under the Density calculation currently 1 g/m3 = 100 g/cm3.  Looks like 1 g/m3 = 1E-6 g/cm3 should be more accurate

Thanx - I have updated the master file.

I´m very close to having an online database and online version of Versaverter running - I hope I can open that to everyone shortly.

Here are corrected density factors for all the standard values.

I also just discovered errors in the density conversion factors in data version 2.2.1.0

Two corrected entries follow, I have not checked all of the density factors, but these two were incorrect:
