About these units
Teragram (Tg)
A teragram equals 1,000 gigagrams, or 10⁹ kilograms. It is widely used in climatology, atmospheric science, and ecology to describe the mass of carbon, nitrogen, methane, or other substances exchanged annually between Earth's systems. For example, global carbon fluxes—movement of carbon between oceans, atmosphere, and biosphere—are typically measured in teragrams. Volcanoes, wildfires, and anthropogenic emissions often release substances on this scale. Tg-level measurements give researchers insight into the stability, sustainability, and long-term trends of Earth's ecosystems.
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.
