"By mass–energy equivalence, the electronvolt is also a unit of mass." though it is true that energy and mass can be converted between eachother, mass units and energy units are not the same thing. You can never write "x electronvolts = y kilograms", It just doesn't work that way.
I always thought electronvolt was an unit of energy and I knew its definition, but in these days I got some doubts because I saw 2 times it was used as an unit of mass: in my school textbook, in an article about the 4 fundamental forces, it was used as a mass unit
In particle physics, multiples of the electronvolt are also used as a units of mass based on the principle of mass–energy equivalence. The dimensionally correct unit of mass for use with the SI would be eV/ c 2 , although the division by the square of the speed of light is often assumed [note 2] and masses quoted simply in megaelectronvolts (MeV, 10 6 eV) or gigaelectronvolts (GeV, 10 9 eV).
The electronvolt (symbol eV) is a unit of energy. It is the amount of energy equivalent to that gained by a single unbound electron when it is accelerated through an electrostatic potential difference of one volt, in vacuo. In other words, it is equal to one volt (1 volt = 1 joule per coulomb) times the (unsigned) charge of a single electron.
Elektronvolt. De elektronvolt (afkorting eV) is een eenheid van energie die vooral gebruikt wordt in de deeltjesfysica, de atoomfysica en de vastestoffysica. Eén eV is de energieverandering die een vrij deeltje met een lading 1e (de elementaire lading e, gelijk aan de lading van een elektron) ondervindt wanneer het in een elektrisch veld een ...
In physics, natural unit systems are measurement systems for which certain physical constants have been set to 1 through nondimensionalization of physical units.For example, the speed of light c may be set to 1, and it may then be omitted, equating mass and energy directly E=m rather than using c as a conversion factor in the typical mass–energy equivalence equation E=mc 2.
The atomic mass constant (m u), one twelfth of the mass a carbon-12 atom, is close to the mass of a proton. To convert to electronvolt mass-equivalent, use the formula: m u = 1 Da = 931.4941 MeV/ c 2 = 0.931 4941 GeV/ c 2 .
