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.
Quintal (Metric)
A quintal (metric) is a unit of mass equal to 100 kilograms.
History/Origin
The metric quintal originated in France in the 19th century as a standard unit of mass for trade and agriculture, replacing older local units. It is part of the metric system established during the French Revolution.
Current Use
The metric quintal is used primarily in agriculture and trade in some countries to measure large quantities of produce, though its use is less common today with the widespread adoption of the kilogram as the standard unit of mass.
