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.
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.
