@Low: The percentages are correct, never said they were wrong however you are still saying assuming that Toriko's human world is the same as Earth's surface in your argument which is wrong as I pointed out. (Our Earth as we know it would only be a fraction of the Human world, less than even a third of it, meaning if you re scaled your argument you'd come to a vastly different conclusion)
lets compare the volumes instead shall we (4/3πr^3) (C=dπ) (d=2r)
Our Earth takes up 3 horizontal spaces on the map meaning roughly .9 block lengths in diameter
worked out Earth's volume comes to ~.1451π block lengths using the same scale
The Map is 19 horizontal blocks across meaning roughly 6 block length in diameter
worked out the planet's volume comes to ~36.868π block lengths using the same scale
Toriko's world is roughly 26x more massive in volume than our Earth, and the diameter is more than 6x that of earth
The red box is our Earth, so once again let me reiterate " Toriko HUMAN world >> Our Earth"
