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.
Hundredweight (Uk)
The hundredweight (UK), or cwt (UK), is a unit of weight equal to 112 pounds avoirdupois, primarily used in the United Kingdom for measuring commodities like produce and livestock.
History/Origin
The UK hundredweight has been used historically in trade and agriculture, originating from the traditional system of weights. It was standardized in the imperial system and has been in use since the 19th century, although its usage has declined with metrication.
Current Use
Today, the UK hundredweight is still used in certain industries such as agriculture and livestock trading, especially in the UK, but it is largely replaced by the metric system in most contexts.
