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.
Centigram
A centigram (cg) is a unit of mass equal to one hundredth of a gram, primarily used for measuring small quantities.
History/Origin
The centigram was introduced as part of the metric system in the 19th century to facilitate precise measurements in science and commerce, especially in contexts requiring small mass units.
Current Use
Today, the centigram is mainly used in scientific, medical, and jewelry contexts where precise small measurements are necessary, although grams are more commonly used in everyday applications.
