Introduction[]
I'll be calculating the biggest explosion Bakugo used during his fight with Uraraka.
Calculation[]
Scan 1
The track around the stadium is stated to have a perimeter of 4 kilometers or 4000 meters.
Semimajor Axis A = 350/2 = 175 px
Semimajor Axis B = 235/2 = 117.5 px
Perimeter = 927.8 px
4000/927.8 = 4.31127398146 m per pixel
Stadium Diameter = 1043.32830351 m
Stadium Radius = 521.664151757 m
Scan 2
Stadium Diameter = 1043.32830351 m (1485 px)
Stadium Top Diameter = 601.40675273 m (856 px)
Scan 3
Stadium Top Diameter = 601.40675273 m (420 px)
Explosion Diameter = 121.713271386 m (85 px)
Explosion Radius = 60.8566356929 m
Y = ((x/0.28)^3)*1000
Y is yield in tons of tnt, and x is radius in kilometers.
Y = ((0.0608566357/0.28)^3)*1000 = 10.2671457102 Tons of TNT
Since the explosion is not nuclear, we need to halve the result.
Explosion Energy = 5.13 Tons of TNT (Large Building level)
