Barrans Jr., Ph. D. > Chemistry Division > Argonne National Laboratory This answer seems to give clear objective numbers, so I'm going to try to work with it, and then go back to some less-exact answers I found on other websites. I have 57.796 kilocalories of Energy for .002015 kilograms of mass. What I want to do is translate to MJ/kg, as this is the unit of measurement in which we compared the other alt fuels, for perspective.
