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.

Long Ton

The long ton (symbol lt) is a unit of mass primarily used in the United Kingdom and some Commonwealth countries. It is equal to 2,240 pounds or approximately 1,016.05 kilograms. The long ton is part of the imperial system and is larger than both the short ton (used in the U.S.) and the metric ton.

Origin:

The long ton originated in medieval England as a standardized measure for trade, particularly for goods like coal and other bulk materials. It was defined as 20 long hundredweight, with each long hundredweight being 112 pounds. This measure became part of the British Imperial System in 1824 and has been widely used in maritime and industrial contexts, especially in the UK, before the metric system was more broadly adopted.
