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.
Stone (Uk)
A stone (st) is a British unit of weight equal to 14 pounds avoirdupois, primarily used for measuring body weight.
History/Origin
The stone has origins in medieval England, where it was used as a practical unit of weight for trade and commerce. Its use has persisted in the UK for measuring human body weight, despite the metric system's adoption elsewhere.
Current Use
Today, the stone is still commonly used in the UK and Ireland for personal weight measurement, especially in the context of health and fitness, although it is largely replaced by kilograms in official and international contexts.
