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.
Slug
A slug is a unit of mass primarily used in the imperial system, equal to approximately 32.174 pounds or 14.5939 kilograms.
History/Origin
The slug was introduced in the 19th century as a unit of mass in the imperial system, named after the animal due to its slow movement, and has been used mainly in engineering and physics contexts within the United States.
Current Use
Today, the slug is primarily used in scientific and engineering calculations in the United States, especially in contexts involving imperial units, but it is largely replaced by the kilogram in most applications worldwide.
