Electron–volt to all other Energy conversions
Electron–volt
Electron volt is amount of kinetic energy gained by single electron accelerating from rest through an electric potential difference of one volt in vacuum.
Historically, the electronvolt was devised as a standard unit of measure through its usefulness in electrostatic particle accelerator sciences, because a particle with electric charge q has an energy E=qv after passing through the potential v; if q is quoted in integer units of the elementary charge and the potential in volts, one gets an energy in eV.
It has a value of one volt, 1 j/c, multiplied by the electron's elementary charge e,1.602176634X 10-19 C Therefore, one electronvolt is equal to 1.602176634 X 10-19 J.
It is a common unit of energy within physics, widely used in solid state, atomic, nuclear, and particle physics. It is commonly used with the metric prefixes milli-, kilo-, mega-, giga-, tera-, peta- or exa- (meV, keV, MeV, GeV, TeV, PeV and EeV respectively).
