About these units
Grain (gr)
The grain, defined as exactly 64.79891 milligrams, is one of the oldest units of mass still in limited use today. Derived from the weight of average cereal grains such as barley or wheat, it became a universal tiny unit used across Europe for coins, medicine, and gunpowder. The grain persists in firearms and ammunition manufacturing because bullet weights are still listed in grains (e.g., a "150-grain bullet"). Reloaders and ballistic engineers rely on the grain as a fine unit suitable for measuring powder charges and projectile masses. It is also used in traditional gold and silver transactions, linking it to the troy system. The grain's longevity highlights how ancient agrarian measures can remain embedded in modern technological practices.
Lepton (Biblical Roman) (lepton)
The lepton, one of the smallest denominations used in Judea under Roman rule, weighed roughly 0.1–0.2 grams. It is best known from the biblical story of the Widow's Mite, representing humility and sacrificial giving. As both a coin and a mass, the lepton represents the minimal economic unit of the ancient Near East.
