In Marvel Cinematic Universe, Captain America throws Ultron through a highway pillar. All credits to Gwynbleiddd, whose only mistake was assuming the pillar was made of conventional concrete instead of reinforced concrete.
Ultron's Leg = 102 px = 60 cm
Green Line = 145 px = 85.3 cm
Blue Line = 304 px = 178.8 cm
Black Line = 380 px = 223.6 cm
A = 42.65 cm
B = 89.4 cm
C = 111.8 cm
I'll treat the crater as a half-ellipsoid.
Volume = 2/3*pi*42.65*89.4*111.8 = 892805.74 cm^3
Energy = 892805.74 x 61.2 = 54639711.29 Joules
Captain America Destroys Pillar = 13.06 Kilograms of TNT (Small Building level)
Just a supporting feat considering that he can hurt people with Building level+ in durability.
