Poundal
The poundal (pdl) is a unit of force in the foot-pound-second (FPS) system, defined as the force required to accelerate a one-pound mass at a rate of one foot per second squared.
History/Origin
The poundal was introduced in the 19th century as part of the FPS system of units, primarily used in engineering and physics before the widespread adoption of the SI system. It was designed to provide a consistent force unit based on imperial units.
Current Use
Today, the poundal is largely obsolete and rarely used outside of historical or specialized engineering contexts. It is mainly referenced for educational purposes or in discussions of imperial units, with the SI unit of force (newton) being the standard.
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.
