eV/c² = kt × 5.609588604e+41
About Kilotonnes
A kilotonne (kt) equals 1,000 metric tonnes (10⁶ kg). In military and geopolitical contexts, nuclear weapon yields are expressed in kilotons of TNT equivalent (kt TNT): the atomic bomb dropped on Hiroshima had a yield of approximately 15 kt TNT. Environmental science uses kilotonnes for reporting regional greenhouse gas inventories, industrial pollutant releases, and annual waste generation. Mining operations quote ore extraction rates in kilotonnes per day. The global atmospheric inventory of various trace gases is reported in kilotonnes.
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.
