I want to make up my own energy units. I am going to call my energy unit $CN$ after my initials. The conversion factor of $CN$ is $1CN=156$cal

How much CN do I have if I start with $954$ joules? Hint: you need $2$ conversion factors to solve this problem. The $2$ are $4\mathrm{.}184$ joules $=1$ cal and $1CN=156$cal.
