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.
Hundredweight (UK) (cwt (UK))
The British hundredweight equals 112 pounds (50.802345 kg). The extra 12 pounds derive from England's historical use of a 14-pound stone. The British hundredweight was used across the former British Empire for trade, taxation, and freight classification. It scales into the long ton (20 cwt = 1 long ton), forming a fully coherent system within imperial measurements. While replaced by metric units in the UK, this unit persists in historical documents, trade archives, and older engineering references.
