A question on converting MeV to GeV

Main Question or Discussion Point

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? :wink:

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
