Nanogram
A nanogram (ng) is a unit of mass equal to one billionth (10^-9) of a gram.
History/Origin
The nanogram was introduced as part of the metric system to measure extremely small quantities, especially in scientific and medical fields, as the need for precise measurement of tiny masses grew with technological advancements.
Current Use
Nanograms are commonly used in scientific research, pharmaceuticals, and environmental testing to measure very small amounts of substances accurately.
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.
