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and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.
Ton (Assay) (Uk)
The ton (assay) (UK), symbol AT (UK), is a traditional unit of weight used primarily for precious metals, equivalent to 31.1034768 grams.
History/Origin
The assay ton originated in the United Kingdom as a standard measure for precious metals, particularly gold and silver, used in assay processes and trading. It has historical roots in the British imperial system and was standardized for trade and assay purposes.
Current Use
Today, the assay ton (UK) is mainly used in the precious metals industry for assay and valuation purposes, especially in the UK and related markets, although it has largely been replaced by the metric gram and troy ounce in general commerce.
