About Electronvolt mass
In particle physics, mass and energy are interchangeable via Einstein's E = mc². The electronvolt (eV) as a mass unit equals the mass equivalent of 1 eV of energy (approximately 1.783 × 10⁻³⁶ kg). Particle masses at the subatomic scale are routinely expressed in MeV/c² or GeV/c² - the proton mass is 938.3 MeV/c², and the electron is 0.511 MeV/c². The Higgs boson, discovered at CERN in 2012, has a mass of approximately 125.25 GeV/c². This unit is exclusively used in high-energy physics and quantum field theory, where conventional mass units like grams would require impossibly small exponents.
About Short Hundredweights
A short hundredweight (cwt, US cwt) equals exactly 100 pounds or approximately 45.359 kg. Used primarily in the United States for commodity trading, it represents the practical 'hundred-pound' unit for measuring coal, agricultural produce, livestock feed, and industrial materials. Commodity markets for cattle, hogs, and grain in the US price their products per hundredweight ($/cwt or $/100 lb). Steel and non-ferrous metal quotations in North America are commonly expressed in dollars per short hundredweight. The 'short' modifier distinguishes it from the UK long hundredweight (112 lb).
