At 64.79891 milligrams, the grain is the smallest traditional unit of weight and is shared across the avoirdupois, troy, and apothecaries' systems. Ammunition manufacturers specify bullet weights in grains (a typical 9mm round uses a 115-grain bullet), and pharmacists historically measured drug doses in grains.

About Carat (ct)

The metric carat equals exactly 200 milligrams and is the universal standard for measuring gemstone weight.
