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 (Us)
A hundredweight (US) is a unit of weight equal to 100 pounds (45.3592 kilograms).
History/Origin
The hundredweight originated in the British Imperial system and was adopted in the United States as a standard unit of weight for trade and commerce, particularly in agriculture and shipping, with the US customary hundredweight defined as 100 pounds.
Current Use
The US hundredweight (cwt) is still used in industries such as agriculture, shipping, and commodity trading to measure bulk quantities of goods like livestock, produce, and other commodities.
