Microgram
A microgram (µg) is a unit of mass equal to one millionth of a gram (10^-6 grams).
History/Origin
The microgram was introduced as part of the metric system to measure very small quantities, particularly in science and medicine, and has been widely used since the 20th century.
Current Use
Micrograms are commonly used today in fields such as pharmacology, nutrition, and chemistry to measure small amounts of substances accurately.
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.
