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 Pennyweights
A pennyweight (dwt or pwt) equals 24 grains or 1/20 of a troy ounce - approximately 1.555 grams. Its name derives from the weight of an English silver penny in the medieval period. Pennyweights are the standard unit used by jewellers and goldsmiths in North America for weighing precious metals: gold, silver, and platinum. When a jeweller quotes the gold weight of a ring or chain, they typically use pennyweights. Gold buyers, refiners, and scrap metal dealers quote prices per pennyweight (often abbreviated 'DWT') when appraising jewellery.
