Re: [Bkchem-user] Chemistry -> Info: Weight is not working mathematical correct

[Beda Kosata]

Hi Jan,

I changed it to 4 decimal places, but do not expect the same result
anyway - BKChem gives 147.1735
Interestingly, I tried to query individual elements on the page you sent
and the values match that of BKChem - however, when I add them up, the
results are different.
I tried 4 other online mass calculators and no two agreed on a single
value - 147.1766, 147.173860, 147.1747, 147.177

So maybe using four decimal places is an overkill anyway.

        Cheers
