Conversion Formula
eV/c² = ct × 1.121917721e+32
About Carats
A metric carat (ct or CD) is exactly 200 milligrams (0.2 g), the universal standard for weighing gemstones. Established internationally in 1907, it replaced fractionally different regional carat weights previously used in different countries. The total weight of a diamond or colored gemstone is always expressed in carats: a 1.00 ct diamond of excellent cut and color can command over $5,000. The Cullinan diamond, the largest gem-quality rough diamond ever found, weighed 3,106.75 carats.
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.
