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 (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).
