Pound (Troy Or Apothecary)
A pound (troy or apothecary) is a unit of weight used primarily for precious metals and gemstones, equivalent to 12 ounces or approximately 373 grams.
History/Origin
The troy pound originated in the medieval French town of Troyes, historically used in the trade of precious metals and gemstones. The apothecary pound was used in pharmacy for weighing medicines and ingredients. Both units have roots in medieval European systems of measurement.
Current Use
The troy pound is still used in the precious metals industry, especially for gold, silver, and gemstones. The apothecary pound is largely obsolete but may still be referenced in historical contexts or traditional practices.
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.
