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).
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.
Stone (US)
The stone (st) is a unit of mass traditionally used in the UK and Ireland, but in the United States, it is less common. In the U.S., the stone is defined as 14 pounds or approximately 6.35 kilograms. It is still used informally in some contexts, particularly in reference to body weight.
The stone as a unit of mass has roots dating back to ancient times, where it was used in various cultures for weighing goods, with the weight of a stone varying by country and commodity. In the UK, the stone was historically used to measure items like wool, and the weight of the stone varied (ranging from 5 to 30 pounds) based on the goods being measured. The U.S. adopted a 14-pound stone in the 19th century, primarily as a way to measure body weight, though it is now largely replaced by the pound for more precise measurements. The 14-pound stone is still used informally in some areas, especially in the context of body weight.
