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.
Exagram
An exagram (Eg) is a unit of mass equal to 10^18 grams, used to measure extremely large quantities of mass.
History/Origin
The exagram is a relatively recent addition to the metric system, introduced to facilitate the measurement of very large masses in scientific and industrial contexts, aligning with the SI prefixes for large units.
Current Use
Exagrams are primarily used in scientific research, astronomy, and large-scale industrial applications to quantify massive amounts of material or celestial bodies.
