Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
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.
