Relation Between Ev And Joule

Electron volt in short Ev is the unit of energy. Joule is a derived unit of energy in the International System of units or SI units. Relation Between Ev And Joule is proportionate. Change in the value of Ev will change the Joule equivalent value in the same proportion.

eV Joule Conversion

eV and Joule are the units of energy in two different systems. Their equivalence can be mathematically expressed as-

1eV = 1.602×10-19 J

Where,

  • eV is electron volt
  • J is Joule

Electron volt

1 electron volt is the energy change that takes place when a charge equal to 1 electron (1.6×10-19C) is moved through a potential difference of 1 volt.

1eV = 1.602×10-19 J

eV

Joule

1 Joule is the work done or energy transferred on an object when a force of 1 newton acts on it in the direction of its motion along a distance of 1 meter.

1 J = 6.2415×1018 eV
