User blog:Therefir/Megumin's explosion magic recalc

I notice the original calc was using pulverization energy, but in the crater there are clearly steams so I'm recalcing this with vaporization energy.

kid/guy = 24.5 px =1.6 m

Width of the crater = 402 px = 26.25 m

Depth of the crater = 62 px = 4.05 m

I will treat the crater as an ellipsoid with a = b = 26.25/2 = 13.125

V = 4/3*π*a*b*c

V = 2922.41 m^3

Vaporization energy is 25700 j/cc

E = 7.5106129e+13 Joules (17894 Tons of TNT) Town level
