### Conversions

What would I multiply "kJ" by to convert it into "J"? Would it be 1000?

### Re: Conversions

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

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.

### Re: Conversions

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.

### Re: Conversions

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?

1 eV= 1.602 * 10^-19 Joules
1000 eV= 1 KeV

Hope this helps~

### Re: Conversions

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.
