Ounce
An ounce (oz) is a unit of weight or mass used primarily in the United States and other countries that use the imperial system. It is equal to 1/16 of a pound or approximately 28.35 grams.
History/Origin
The ounce has origins in ancient Roman and medieval systems of weight measurement. It was historically used in various forms across different cultures, with the modern avoirdupois ounce standardized in the 14th century in England to facilitate trade and commerce.
Current Use
Today, the ounce is commonly used to measure food ingredients, precious metals, and other small quantities of weight in the United States and other countries using the imperial system. It is also used in the context of jewelry, cooking, and postal services.
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.
