Attogram
An attogram (ag) is a unit of mass equal to 10^-18 grams, used to measure extremely small quantities.
History/Origin
The attogram was introduced as part of the metric system's expansion to include smaller units for scientific measurements, particularly in fields like nanotechnology and molecular biology, during the 20th century.
Current Use
Attograms are primarily used in scientific research to quantify very small masses, such as individual molecules or nanoparticles, and are part of the SI units for precise measurements in advanced scientific applications.
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.
