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.
Quarter (Uk)
A quarter (qr) is a traditional unit of weight used in the UK, typically equal to one-quarter of a hundredweight, or 28 pounds (approximately 12.7 kilograms).
History/Origin
The quarter has historical roots in British measurement systems, originating from the need to divide larger weights into manageable parts. It was commonly used in trade and agriculture before the adoption of the metric system.
Current Use
Today, the quarter is largely obsolete in official measurement but may still be used informally in certain industries such as agriculture and livestock to denote weight, especially in the UK.
