Hectogram
A hectogram (hg) is a unit of mass equal to 100 grams.
History/Origin
The hectogram is part of the metric system, introduced in the 19th century as a decimal-based system for standardizing measurements, primarily used in scientific and everyday contexts.
Current Use
The hectogram is used in some countries for measuring food and other small quantities, especially in the context of nutrition labels and grocery shopping, but is less common than grams and kilograms.
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.
