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.
Stone (Uk)
A stone (st) is a British unit of weight equal to 14 pounds avoirdupois, primarily used for measuring body weight.
History/Origin
The stone has origins in medieval England, where it was used as a practical unit of weight for trade and commerce. Its use has persisted in the UK for measuring human body weight, despite the metric system's adoption elsewhere.
Current Use
Today, the stone is still commonly used in the UK and Ireland for personal weight measurement, especially in the context of health and fitness, although it is largely replaced by kilograms in official and international contexts.
