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.
Proton Mass
The proton mass (m_p) is the mass of a proton, a subatomic particle found in the nucleus of an atom, approximately 1.6726219 × 10⁻²⁷ kilograms.
History/Origin
The proton mass was first measured in the early 20th century through experiments involving atomic and nuclear physics, notably by Ernest Rutherford and subsequent researchers refining the value through scattering experiments and mass spectrometry.
Current Use
The proton mass is used as a fundamental constant in physics and chemistry, serving as a standard unit of mass in atomic and nuclear calculations, and is essential in defining atomic mass units and understanding nuclear reactions.
