Ton (Assay) (Uk)
The ton (assay) (UK), symbol AT (UK), is a traditional unit of weight used primarily for precious metals, equivalent to 31.1034768 grams.
History/Origin
The assay ton originated in the United Kingdom as a standard measure for precious metals, particularly gold and silver, used in assay processes and trading. It has historical roots in the British imperial system and was standardized for trade and assay purposes.
Current Use
Today, the assay ton (UK) is mainly used in the precious metals industry for assay and valuation purposes, especially in the UK and related markets, although it has largely been replaced by the metric gram and troy ounce in general commerce.
Femtogram
A femtogram (fg) is a unit of mass equal to 10^-15 grams.
History/Origin
The femtogram was introduced as part of the metric system's extension to measure extremely small masses, particularly in scientific fields such as chemistry and biology, during the 20th century as measurement technology advanced.
Current Use
Femtograms are used in scientific research to measure tiny quantities of substances, such as in molecular biology, nanotechnology, and materials science, where precise measurement of very small masses is required.
