Electron Mass (Rest)
The electron mass (rest) is the invariant mass of an electron, approximately 9.10938356 × 10⁻³¹ kilograms, representing the mass of an electron at rest.
History/Origin
The electron mass was first measured in the early 20th century through experiments involving cathode rays and later refined with advancements in particle physics, establishing it as a fundamental constant in physics.
Current Use
The electron mass is used in calculations involving atomic and subatomic physics, quantum mechanics, and in defining units related to particle properties, such as in the 'Weight and Mass' converter for scientific and educational purposes.
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.
