You can do the reverse unit conversion from gigajoule to electronvolt, or enter any two units below:
In physics, the electron volt (eV) is a unit of energy. By definition, it is equal to the amount of kinetic energy gained by a single unbound electron when it accelerates through an electrostatic potential difference of one volt.
The SI prefix "giga" represents a factor of 109, or in exponential notation, 1E9.
So 1 gigajoule = 109 joules.
The definition of a joule is as follows:
The joule (symbol J, also called newton meter, watt second, or coulomb volt) is the SI unit of energy and work. The unit is pronounced to rhyme with "tool", and is named in honor of the physicist James Prescott Joule (1818-1889).
