About these units
Deuteron Mass (m๐น)
A deuteron is the nucleus of deuterium, composed of one proton and one neutron. Its mass is approximately 3.343583719 ร 10โปยฒโท kilograms, slightly less than the combined mass of its constituents due to binding energy. Deuterons are essential in nuclear fusion research, heavy water production, and astrophysical studies. They serve as a stepping stone in stellar nucleosynthesis, where hydrogen fuses into helium in the cores of stars. Understanding deuteron mass provides insight into the fundamental nuclear forces, fusion energy potential, and the behavior of matter under extreme conditions.
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.
