Milligram
A milligram (mg) is a unit of mass equal to one thousandth of a gram.
History/Origin
The milligram has been used in scientific and medical contexts for precise measurement of small quantities, especially in pharmacology and chemistry, with its origins linked to the metric system established in the 18th century.
Current Use
Today, the milligram is widely used in pharmaceuticals, nutrition, and scientific research to measure small amounts of substances accurately.
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.
