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.
Quintal (Metric) (cwt (m))
The metric quintal, equal to 100 kilograms, is commonly used in agriculture for measuring harvest yields, livestock feed, and bulk commodities such as grains, sugar, and potatoes. Its simplicity makes it popular in countries with strong agricultural sectors. Farmers, traders, and cooperatives find the quintal more intuitive for medium-sized loads than kilograms or metric tons. Though not an SI unit, it remains deeply embedded in agricultural commerce throughout Europe, Asia, and Latin America.
