Pound
The pound (lbs) is a unit of weight or mass commonly used in the United States and other countries, equivalent to 16 ounces or approximately 0.453592 kilograms.
History/Origin
The pound has origins in ancient Roman and Anglo-Saxon systems, evolving over centuries into its current form. It was historically based on various standards, including the Tower pound and the avoirdupois pound, with the latter becoming the standard in most countries.
Current Use
Today, the pound is primarily used in the United States for measuring body weight, food products, and other goods. It remains a standard unit in certain industries and is part of the imperial and US customary measurement systems.
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.
