Introduction[]
I'll be doing three MHA calcs today, the first one I promised to do when the anime got to this point and it has.
The hole made in the street was impossible to calc since we never saw how big the hole was in the manga before Izuku had jumped through it and made it bigger. However the anime does show us so this can be done now.
The second is a Kinetic Energy calc with a giant villain that Nejire took down.
The third is just a standard calc for base Rikiya when he destroyed part of a building.
Calculation[]
Feat 1[]
Scan 1
Izuku Height = 166 cm (30 px)
This is Toga transformed into Izuku, her height changes to match the person she's transformed into so this should be fine.volume-calculator.html
Hole Diameter = 1676.6 cm (303 px)
Hole Radius = 838.3 cm
Scan 2
Random Guy Height = 175 cm (18 px)
Hole Depth = 1244.44444444 cm (128 px)
Volume = 2747415336.6479 cm^3
I'll use V.Frag of concrete just like original did.
Violet Fragmentation of concrete is 20 J/cm^3
Energy = 2747415336.6479 x 20 = 54948306733 Joules, 13.13 Tons of TNT (City Block level)
Feat 2[]
Scan 1
Window Height = 1.5 m or 150 cm (19 px)
Giant Man Head = 813.157894737 cm (103 px)
The average person is 7.5 heads tall.
Giant Height = 813.157894737 x 7.5 = 6098.68421053 cm or 60.98684210530001 m
Average Male Height = 175 cm
Ideal Weight = 76.6 kg
Now we can calculate the weight of his giant form.
Giant Man Weight = (6098.68421053 /175)^3*76.6 = 3242075.03633 kg (Class M)
I'll use this scene in the anime to find the giant's running speed.
Scan 2
Window Height = 1.5 m (25 px)
Screen Height = 918 px
Angular Size = object size*panel height in pixels/[object height in pixels*2*tan(70deg/2)]
1.5*1080/[25*2*tan(70deg/2)] = 46.2719954184 m
He travels that distance in 3 frames, the video runs at 30 fps.
Timeframe = 3/30 = 0.1 seconds
Speed = 46.2719954184/0.1 = 462.719954184 m/s, Mach 1.3 (Supersonic)
Kinetic Energy = 347079947481 Joules, 82.95 Tons of TNT (City Block level+)
Feat 3[]
Window Height = 150 cm (57 px)
Building Height = 1105.26315789 cm (420 px)
Building Length = 889.473684211 cm (338 px)
Building Width = 47.3684210526 cm (18 px)
Volume = 46568012.829653 cm^3
I'll use the V.Frag of reinforced concrete.
Violent Fragmentation of reinforced concrete is 41.4 J/cm^3
Energy = 46568012.829653 x 41.4 = 1927915731.15 Joules, 0.46 Tons of TNT (Building level)
