Convert Grain to Stone (UK)
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 (UK)
The stone (st) is a unit of mass used primarily in the United Kingdom and Ireland to measure body weight. It is defined as 14 pounds or approximately 6.35 kilograms. The stone is still commonly used in the UK for personal weight, especially in everyday contexts like medical and fitness settings.
The stone has ancient origins, dating back to the medieval period. Historically, the weight of a stone varied depending on the commodity being measured, ranging from 5 to 30 pounds. For example, in England, the stone was used to measure wool, and different types of goods had their own stone weights. In 1300, a standardized 14-pound stone was adopted for use in the wool trade. Over time, this 14-pound definition became the standard, and the stone was widely used in the UK for measuring body weight, a tradition that continues today.
