Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
Teragram
A teragram (Tg) is a unit of mass equal to one trillion grams or 10^12 grams.
History/Origin
The teragram is part of the metric system and was introduced as a larger unit for measuring very large masses, especially in scientific contexts, to facilitate easier expression of large quantities.
Current Use
Teragrams are used primarily in scientific fields such as environmental science, geology, and astronomy to quantify large masses, like global emissions or mineral deposits.
