Gram
The gram (g) is a metric unit of mass equal to one thousandth of a kilogram.
History/Origin
The gram was originally defined in 1795 as the mass of one cubic centimeter of water at its maximum density. It became part of the metric system established in France and was later standardized as part of the International System of Units (SI) in 1960.
Current Use
The gram is widely used worldwide for measuring small masses in everyday life, science, and industry, especially in contexts like food labeling, pharmaceuticals, and laboratory measurements.
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.
