Electronvolt
IUPAC RECOMMENDATIONS 2013
Non-SI unit of energy (symbol eV) defined as the energy acquired by a particle containing charge equal to elementary charge accelerated through a potential difference of one volt. Note: An electronvolt is equal to 1.602176565(35) ? 10¹⁹ J where the digits in parentheses indicate the estimated uncertainty in the final two digits of the value.
