Ounce
An ounce (oz) is a unit of weight or mass used primarily in the United States and other countries that use the imperial system. It is equal to 1/16 of a pound or approximately 28.35 grams.
History/Origin
The ounce has origins in ancient Roman and medieval systems of weight measurement. It was historically used in various forms across different cultures, with the modern avoirdupois ounce standardized in the 14th century in England to facilitate trade and commerce.
Current Use
Today, the ounce is commonly used to measure food ingredients, precious metals, and other small quantities of weight in the United States and other countries using the imperial system. It is also used in the context of jewelry, cooking, and postal services.
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.
