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.
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.
