Planck Mass
The Planck mass (m_P) is a fundamental physical constant representing a mass scale derived from natural units, approximately 2.176 × 10^-8 kilograms.
History/Origin
Introduced by Max Planck in 1899 as part of his system of natural units, the Planck mass emerged from combining fundamental constants to define a universal mass scale in theoretical physics.
Current Use
The Planck mass is primarily used in theoretical physics, especially in quantum gravity and high-energy physics, to express natural units and scale phenomena near the Planck scale.
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metals industry for assay and valuation purposes, especially in the UK and related markets, although it has largely been replaced by the metric gram and troy ounce in general commerce.
