  • energia SI ühikutest sõltumatult määratletud ühiku nimetus/tähis
  • name of the unit of energy equal to the difference in potential energy of an electron in two positions with electric potential difference of one volt
  • name/symbol of the off-system unit of energy with respected to the SI
elektronvolt preferred
Usage examples
  • Elektronvolt on aatomi- ja tuumafüüsikas laialdaselt kasutatav energiaühik, mis võrdub energiaga, mille elektron (elementaarlaengut kandev laetud osake) omandab, kui elektripotentsiaal elektroni asukohas suureneb ühe voldi võrra.
