Pound
The pound (lbs) is a unit of weight or mass commonly used in the United States and other countries, equivalent to 16 ounces or approximately 0.453592 kilograms.
History/Origin
The pound has origins in ancient Roman and Anglo-Saxon systems, evolving over centuries into its current form. It was historically based on various standards, including the Tower pound and the avoirdupois pound, with the latter becoming the standard in most countries.
Current Use
Today, the pound is primarily used in the United States for measuring body weight, food products, and other goods. It remains a standard unit in certain industries and is part of the imperial and US customary measurement systems.
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.
