Convert Grain to Short Ton

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.

The short ton originated in the U.S. as a way to standardize weight measurements, particularly for bulk commodities like coal and steel. It is called "short" to distinguish it from the long ton (also known as the imperial ton), which is used in the UK and equals 2,240 pounds. The short ton became widely used in the United States during the 19th century as part of the U.S. customary system of measurements.
