Grains (gr)
Definition
A grain (gr) is one of the oldest units of mass, equal to approximately 64.799 milligrams or 1/7000 of a pound avoirdupois.
History
The grain is historically based on the weight of a single cereal grain (wheat or barley). It has been used since ancient civilizations and was the basis for many historical weight systems including the troy and apothecaries' systems.
Current use
Grains are used in ammunition and firearms (bullet and powder charge weights), archery (arrow weights), and some pharmaceutical compounding. The gold and jewelry industries use troy grains.
Metric Tons (t)

A metric ton (t), also called a tonne, is a unit of mass equal to 1,000 kilograms or approximately 2,204.62 pounds.
History
The metric ton was introduced as a practical large-scale unit within the metric system. It was designed to replace various regional ton measures and provide a decimal-based alternative to the long and short tons used in English-speaking countries.
Current use
Metric tons are the global standard for measuring bulk commodities (steel, grain, coal), vehicle weight, shipping cargo, CO₂ emissions, and industrial production output.
