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metals industry for assay and valuation purposes, especially in the UK and related markets, although it has largely been replaced by the metric gram and troy ounce in general commerce.
Petagram
A petagram (Pg) is a unit of mass equal to 10^15 grams or one quadrillion grams.
History/Origin
The petagram was introduced as part of the metric system's prefixes to represent extremely large masses, following the adoption of the International System of Units (SI). It is derived from the prefix 'peta-' which denotes 10^15.
Current Use
The petagram is primarily used in scientific contexts to quantify very large masses, such as in astronomy and geology, but is rarely used in everyday measurements.
