Kiloelectron volt to Joule

1.23 asks "The gamma-ray photons emitted by the nuclear decay of a technetium-99 atom used in radio-pharmaceuticals have an energy of 140.511 keV. Calculate the wavelength of these gamma-rays."

What is the conversion from an electron volt to a Joule?

1 electron volt is equal to 1.602 x 10^19 joule

Re: Kiloelectron volt to Joule

1.602 x 10^19 joule = 1 electron volt

Re: Kiloelectron volt to Joule

I am pretty sure that this conversion factor is on the equation sheet given to us during tests as well.

Since 1 eV=1.602*10^19 J, 1keV=1.602*10^22 J.
