What website can I use to convert the volume of an explosion to that of joules?

And to be more specific, what is the formula for calculating the size of an explosion, with said explosion destroying the planet
 
You would need to find out the density of the energy and then find the radius of the area and use the volume formula of a sphere. Times the energy density by the volume to get area.

I used this forumla: 4*U*(Er/Br)^2 = E

GBE of earth is 2.49×10^32 J

Er is 7.06*10^16m (from the calc)

Br of earth is 6,371km or 6,371,000m

4*(2.49×10^32)*((7.06*10^16)/(6,371,000))^2 = 1.2230762e+53 J or 1.2230762 GigaFoe (Solar System level)

Sorry. My mistake. I did not read your second message completely. But I believe the GBE would constitute as enough.
