In the unit "keV", "k" stands for kilo(10^3) and "eV" stands for electron volt, a unit of energy equal to the energy acquired by an electron in being accelerated through a potential difference of 1 volt. Therefore, "keV" is kilo-electron volt. For problem 1B5, you will need to convert "keV" to "J". 1 eV = 1.602 x 10^-19J

KeV stands of Kilo electronvolt.
To convert you just need to know:
1) 1 kilo- is equal to 1000 base units (in this case eV).
2) 1eV is equal to 1.60218x10^-19 joules
I don't remember that they had an example in the textbook's section or displayed the conversion of these units, so I was confused as well.
