Seth,
Regarding your question of November 28th.
"Is a carat the same as a grain?"
No. A troy, or long, or avoirdupois carat is always 1/144 of the weight of an ounce. A grain is not.
1 av.ct. = 1/144 av.oz.
1 long ct. = 1/144 long oz.
1 troy ct. = 1/144 troy oz.
1 grain = 2/875 av.oz.
1 grain = 2/900 long oz.
1 grain = 2/960 troy oz.
