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.
Microgram
A microgram (µg) is a unit of mass equal to one millionth of a gram (10^-6 grams).
History/Origin
The microgram was introduced as part of the metric system to measure very small quantities, particularly in science and medicine, and has been widely used since the 20th century.
Current Use
Micrograms are commonly used today in fields such as pharmacology, nutrition, and chemistry to measure small amounts of substances accurately.
