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 Long Tons
A long ton (UK ton, displacement ton) equals 2,240 pounds or exactly 1,016.0469088 kg. The standard ton in the United Kingdom and Commonwealth countries, it equals 20 long hundredweights of 112 lb each. Naval architecture and ship displacement are specified in long tons: the displacement of a warship or cargo vessel is the weight of water it displaces, expressed in long tons. The Titanic had a displacement of approximately 52,310 long tons. British agricultural, mining, and coal trade statistics from the 18th through mid-20th centuries used long tons exclusively.
