Volt is the unit of electric potential difference and electron volt is the unit of energy

Volt: It is 1J of work done in moving unit positive charge from one point to another, keeping electrostatic equilibrium. 
					1volt=1 joule / 1 coulomb
Electron volt: The energy gained or lost by an electron as it moves between two points having potential difference of one volt.
				1eV= 1e x 1V = 1.6 x 10-19C x 1 V
				1eV = 1.6 x 10-19 C
