Convert MeV/cm^3 to rads

Homework Equations

I wish I knew..

The Attempt at a Solution

I tried looking up the unit conversions, but find nothing that connects them, I know rads is connected to the Gray which is J/Kg but can't connect it to the MeV/cm^3. Any ideas?

Hi ~Sam~!

rad is the old cgs unit, gray (small "g") or Gy (= 100 rad) is the SI unit … see http://en.wikipedia.org/wiki/Gray_(unit)"

MeV/cm³ has the wrong dimensions, so you can't convert it to rad or Gy …

MeV/cm³ would convert to Gy times density (J/kg times kg/m³)

Gy measures absorbed radiation per mass, MeV/cm³ measures absorbed radiation per volume
