Default A reliable conversion for grams to grain.

Hey guys,

What you you guys use as a conversion factor for grams to grain weight? It seems even this isn't a standard. I've downloaded charts and weighed both Airflo and Rio shooting heads. I'm coming up with anywhere from 14.5-15.75 grains per gram How can they be this far off???

1 gr= 64.79891 mg per Avoirdupois

1000mg= 1gm= 15.432358 gr.

I just rouded off to 15 gr.

Now here's the kick in the pants:
My Airflo 630gr head weighs 40 grams that works out to 15.75gr per gram.

Guess I'll split the difference and use 15 as well.
