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.
Teragram
A teragram (Tg) is a unit of mass equal to one trillion grams or 10^12 grams.
History/Origin
The teragram is part of the metric system and was introduced as a larger unit for measuring very large masses, especially in scientific contexts, to facilitate easier expression of large quantities.
Current Use
Teragrams are used primarily in scientific fields such as environmental science, geology, and astronomy to quantify large masses, like global emissions or mineral deposits.
