Grain

The grain (gr) is a unit of mass used in both the imperial system and the U.S. customary system. It is defined as 1/7000 of a pound or approximately 64.79891 milligrams. The grain is one of the smallest units of mass commonly used and is primarily employed in measuring the weight of precious metals, gemstones, and ammunition (such as bullets).

Origin:

The grain traces its origins to ancient times and was originally based on the weight of a single grain of cereal, such as barley or wheat, which was used as a reference for small weight measurements. The term "grain" comes from the Latin "granum", meaning "grain" or "seed." The grain was used as a standard measure in ancient civilizations, including the Romans, and its use continued throughout medieval Europe. Over time, it was standardized in the 14th century as part of the Avoirdupois system and has remained in use for very precise measurements in modern times, especially in scientific fields, medicine, and the firearm industry.

Tonne

The tonne (t) is a unit of mass equal to 1,000 kilograms (1,000 kg) or 1 megagram (1 Mg). It is part of the metric system but is not an SI unit. However, it is accepted for use with the SI due to its widespread application in measuring large masses, such as in industry and transportation.

Origin:

The tonne was introduced in the 1790s during the creation of the metric system in France. It was established as a convenient way to represent large quantities of mass, aligning with the decimal-based nature of the system. The term "tonne" is derived from the Old French word "tonne", meaning a large cask or barrel, reflecting its use in measuring heavy loads. Over time, it became a standardized unit used globally in fields like shipping, agriculture, and environmental science.
