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.
Hundredweight (Uk)
The hundredweight (UK), or cwt (UK), is a unit of weight equal to 112 pounds avoirdupois, primarily used in the United Kingdom for measuring commodities like produce and livestock.
History/Origin
The UK hundredweight has been used historically in trade and agriculture, originating from the traditional system of weights. It was standardized in the imperial system and has been in use since the 19th century, although its usage has declined with metrication.
Current Use
Today, the UK hundredweight is still used in certain industries such as agriculture and livestock trading, especially in the UK, but it is largely replaced by the metric system in most contexts.
