Convert grain to ton (assay) (US)
Please provide values below to convert grain [gr] to ton (assay) (US) [AT (US)], or Convert ton (assay) (US) to grain.
1 gr = 0.00222167691429 AT (US). To convert grain to ton (assay) (US), multiply the value by 0.00222167691429; to go the other way, divide by it (1 AT (US) = 450.110451961 gr). Both units measure weight and mass and appear in everyday as well as technical calculations, so switching between them quickly is often useful.

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and precious metals, and is recognized as a unit of mass in the apothecaries' system, although it has largely been replaced by grams in most contexts.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) (Us)
The ton (assay) (US), symbolized as AT (US), is a unit of weight used primarily in the assay and precious metals industry, equivalent to 31.1034768 grams.
History/Origin
The assay ton originated in the United States as a standardized measure for precious metal content in assays, aligning with the metric system but retaining the traditional 'ton' terminology for industry consistency.
Current Use
Today, the assay ton (AT US) is used mainly in the precious metals industry for assay purposes, especially in the context of gold and silver purity measurements, and is part of weight and mass conversions within the 'Common Converters' category.
