About Grains
A grain (gr) is the smallest unit in both the avoirdupois and troy weight systems, equal to exactly 64.79891 milligrams. Originally defined as the mass of a single grain of barley or wheat from the middle of an ear, it has been a standard of weight since ancient times. Today, grains are used to weigh gunpowder charges and bullets (a standard .308 rifle bullet weighs 168 gr), pharmaceutical preparations in apothecary compounding, and the fineness of gold alloys. Arrowhead and fishing hook weights are also specified in grains.
About Short Tons
A short ton (also known as a US ton) equals exactly 2,000 pounds or approximately 907.185 kg. It is the standard ton in the United States for coal, scrap metal, aggregate, freight, and agricultural commodities. US electricity, energy, and mining production statistics are reported in short tons or millions of short tons (MMst). American trucking weight limits, rail car capacities, and bulk cargo specifications use short tons. When Americans refer to a 'ton' without qualification, they almost always mean the short ton.
