The ounce (oz) here is the avoirdupois ounce, one sixteenth of a pound, or exactly 28.349523125 grams. It is used in the United States for food packages, postage and small goods, and it is not the same as the troy ounce used for precious metals or the fluid ounce, which measures volume.
The grain (gr) is exactly 64.79891 milligrams and is the base of the avoirdupois, troy and apothecaries weight systems, originally based on a grain of barley. It is used today mostly for the weight of bullets and powder charges in ammunition.
