User blog:Muhammedmco/Strike The Blood - Crater from the beginning

Introduction
Feat in Question (Yukina was the one who done it by the way during her clash with the guy with the axe)

Calc
Yukina is 1.56 m.

She is 52 px.

1.56/52 = 0.03 m/px.

Crater's Diameter = 520 px = 15.6 meters.

Crater's Radius = 7.8 meters.

The crater's shape looks like a sphere.

Volume of crater = 1987.7987692618 m^3 = 1987798769.2618 cm^3.

Since the floor remained intact, and there is only cracks in it, i'm gonna use Violent Fragmentation.

E = (1987798769.2618)*(69)= 1.371581151e11 Joules = 32.78157626673 Tons of TNT (City Block level)

Conclusion
Crater from the beginning = 32.78157626673 Tons of TNT (City Block level)
