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.
Gerah (Biblical Hebrew) (gerah)
A gerah, approximately 0.57 grams, is the smallest unit in the Hebrew weight system. 1 shekel = 20 gerahs Gerahs were used for minute quantities of precious metals or spices for ritual purposes. Biblical texts refer to gerahs in the context of sanctuary offerings and priestly duties. The gerah illustrates the fine-grained precision required for temple rituals and daily commerce in the ancient Near East.
