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metals industry for assay and valuation purposes, especially in the UK and related markets, although it has largely been replaced by the metric gram and troy ounce in general commerce.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
