Hundredweight (Us)
A hundredweight (US) is a unit of weight equal to 100 pounds (45.3592 kilograms).
History/Origin
The hundredweight originated in the British Imperial system and was adopted in the United States as a standard unit of weight for trade and commerce, particularly in agriculture and shipping, with the US customary hundredweight defined as 100 pounds.
Current Use
The US hundredweight (cwt) is still used in industries such as agriculture, shipping, and commodity trading to measure bulk quantities of goods like livestock, produce, and other commodities.
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.
