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.
Hectogram
A hectogram (hg) is a unit of mass equal to 100 grams.
History/Origin
The hectogram is part of the metric system, introduced in the 19th century as a decimal-based system for standardizing measurements, primarily used in scientific and everyday contexts.
Current Use
The hectogram is used in some countries for measuring food and other small quantities, especially in the context of nutrition labels and grocery shopping, but is less common than grams and kilograms.
