Its about this calc made by Lina Shields, the scalling and physics is well done, but when were calculed the elipsoide volume was used the diameter of the elipsoide rather than the radious, making the result 8 times higher than it should, the real result would be ~1.6 m^3; another mistake (not as big tho) is the one of the 3 diameters of the elipsoide were assuming, being the the 1.52 m used, wherever one is used that could increase/decrease the result in 15.4%
The other part is that the mass of the diamond created were already calculated in being ~1200 kg, when the mass of the granite were calculed in ~3600 kg (done with the correction from above), that means that only 1/3 of the granite were turned into diamond, making the result another 3 times bigger than it should.
So, I was waiting for Lina to suggest the changes since doesn't seems appropiate to use his scaling to re-calc, at least not without his permission. I also found a way to compensate the area of non-circular circunferences, but need to talk that with Lina or a calc member.
EDIT: Will wait a pair of hours, then I'll made the blog with the compensations.
Oh right, Kkapoios has created a new blog about converting diamonds where physics appears to have more sense, this will reduce the result to 11.283 tnt tons. I'll change the OP and hopefully we can settle this for one time for all
