Grain
A grain is a unit of mass traditionally used to measure small quantities, primarily in the context of precious metals, pharmaceuticals, and firearms.
History/Origin
The grain dates back to ancient times and was originally based on the weight of a single seed of a cereal grain, such as barley. It has been used since the Middle Ages and was standardized in the apothecaries' system.
Current Use
Today, the grain is mainly used in the measurement of bullets, gunpowder, and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.

A long ton, also known as the imperial ton or UK ton, is a unit of weight equal to 2,240 pounds or 1,016.0469 kilograms.
History/Origin
The long ton originated in the United Kingdom as a standard measurement for large quantities of goods and materials, particularly in shipping and trade, during the 19th century. It was used alongside other imperial units before the adoption of the metric system.
Current Use
