User blog:Muhammedmco/Busou Renkin - Washio causes an explosion

Introduction
Feat in Question

Calc
In this calc, i will assume 1 px in a situation, and i will assume another scaling given Washio's pixel height from this scan.

1st Method
Washio is 1.95 m.

1.95/1 = 1.95 m/px.

Radius of explosion = 185 px = 360.75/2 = 180.375 meters.

They were at ground level, so...

W = R^3*((27136*P + 8649)^(1/2)/13568 - 93/13568)^2

P = 20 psi = 1.37895 bars.

W = 471.6442537 tons of TNT (Multi-City Block level)

2nd Method
This time, i will use Washio's pixel height from another scan that came right after the page that has the feat in the manga.

Washio is 1.95 m.

He is 254 px.

1.95/254 = 0.007677165354 m/px.

Radius of explosion = 185 px = 1.420275591/2 = 0.7101377953 meter.

They were at ground level, so...

W = R^3*((27136*P + 8649)^(1/2)/13568 - 93/13568)^2

P = 20 psi = 1.37895 bars.

W = 2.878149824e10-5 tons of TNT (Wall level)

Okay. I think that the first way is the legit one, since Kazuki had just done a Large Building level feat, and he and Tokiko had hard time dealing with him.

Conclusion
Washio causes an explosion = 471.6442537 tons of TNT (Multi-City Block level)
