Energy Unit of keV

Postby Xingzheng Sun 2K » Tue Oct 16, 2018 1:00 am

In homework problem 1.23, the energy is in the unit of keV. I wonder what is its relation to joules and how often do we use it.

Hi,

keV stands for kilo electronvolts, so you want to convert that to just electronvolts before using the conversion factor for Joules which is 1 eV/ 1.60218 * 10^-19 J. I'm not sure how often we will use keV but I'm pretty sure the conversion is given on our equations and constants sheet for tests. Hope that helps!
