a question on converting MeV to GeV


hi - I'm stuck on a question...
use the graph to calculate the binding energy of uranium 235 nucleus:

the graph gave 7.6MeV

i need to give my answers to GeV - and the mark scheme told me to 7.6Mev x 235 to give 1.8GeV??

i thought you just multiplied by 10^3.

what happened?

thanks!

Welcome to PF funnybunny,

Are you sure that the graph didn't show binding energy per nucleon?

yeh..it did...woops
but even if you multiplied it by 235, giving the total binding energy, it's still in MeV

i did 7.6x10^6 x 235 x 10^3 which gave 1.8x10^12...which is waay too big
