Yes. If you do the following dimensional analysis:

1 kJ * 1000 J/1kJ

the kJ will cancel out the other kJ and you will end up with J

1 kJ * 1000 J/1kJ

the kJ will cancel out the other kJ and you will end up with J

Also for future reference k which is kilo is equivalent to 1000 of meters, liters, joules, etc. So kilo always equals 1000 of the base unit.

do we have to memorize the conversion of Electron-volts to Joules for tests and/or quizzes?

I dont think we need to memorize such values but I would know how to do it.

Do we get a formula sheet with conversions between things like electron volts and joules and. other conversions that we might need to know? Or are these things we should be memorizing?

What is the conversion from Kev to J?

1 eV= 1.602 * 10^-19 Joules

1000 eV= 1 KeV

Hope this helps~

This number is on the back of the periodic table from the Course Reader Store along with all the other constants so I would imagine that we don't need to memorize it.
