in Google. Google calculator is pretty awesome as well.

“about six ounces of matter will be completely transformed into energy”

Shouldn’t the m in question be the difference in mass between the fuel and the end products of fission?

Wolfram Alpha to the rescue again, in my attempt to understand an example fission reaction:
(mass of U236 – (mass of Ba131 + mass of Kr92))/(mass of U236)
returns
.055974
So only about a 20th of the initial fuel mass is actually converted in this case.

e = mc^2 1 oz

It returned 707.8 GWh (Gigawatt-hours)

It’s amazing how Alpha can figure out how to interpret these queries!
