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.
Ton (Long)
A long ton, also known as the imperial ton or UK ton, is a unit of weight equal to 2,240 pounds or 1,016.0469 kilograms.
History/Origin
The long ton originated in the United Kingdom as a standard measurement for large quantities of goods and materials, particularly in shipping and trade, during the 19th century. It was used alongside other imperial units before the adoption of the metric system.
Current Use
Today, the long ton is primarily used in the United Kingdom and some Commonwealth countries for measuring large quantities of freight, cargo, and in certain industrial contexts. It is less common internationally, having been largely replaced by the metric ton (tonne).
