Hello, I need the stopping power for a proton ion gun through Boron-11 sheet 1mm thick.

I have the following table obtained from here:

https://www-nds.iaea.org/stopping/stopping_hydr.html

Where the unit is in 1-15*eV*cm2/atom:

Then I calculated for 600keV protons at table 5.1eV*cm2/atom.

I calculated for Boron wich density is 2080kg/m3 and atomic number 11 a density of 1.139atoms/m3

So the stopping power should be:

5.1*1e-6 (MeV/eV) * 1e-4 (cm2/m2) /1.1389 *.001=58e6 MeV

That is too much (at least 1e6 times), what I did wrong?
