Exagram
An exagram (Eg) is a unit of mass equal to 10^18 grams, used to measure extremely large quantities of mass.
History/Origin
The exagram is a relatively recent addition to the metric system, introduced to facilitate the measurement of very large masses in scientific and industrial contexts, aligning with the SI prefixes for large units.
Current Use
Exagrams are primarily used in scientific research, astronomy, and large-scale industrial applications to quantify massive amounts of material or celestial bodies.
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.
