I have spent basically a month testing this out, so bear with me. The results could be too low or high for all I know.
I have found another way to calculate feats that are on a different level from our regular j/cc equations. This is tensile and compressive strength. Essentially, tensile strength is how much force an object can take before being torn apart completely. Compressive strength is how much force an object can take before compacting into a shape incomparable to its former shape.
- This is an actual method used by scientists and can be measured in Megapascals (Mpa) and pounds per square inch (psi.) A lot of materials have a Mpa and psi value, and this is mainly why this formula seems pretty reliable. And as you all know, a force can be converted into energy as long as there's a measurable distance the force crossed.
Anyways, I'll be testing this equation out with one of Midoriya's most famous smashes of all time. His first ever Smash.
So, one of our main objectives here would be to find exactly how much steel Midoriya compressed/destroyed and what that would yield in terms of force.
It'd be fair to assume the Zero Pointer is made out of stainless steel. It has a pretty high compressive strength and a decent tensile strength in the real world, so it should be an ideal metal. Stainless steel has a compressive strength of 226,259 pounds per square inch,
according to this article.
- We'll have to apply this value over the area he destroyed, since it's y'know, a force displayed over one inch.
Again, we’ll have to find how much area Midoriya’s punch here is destroyed. For that, we will be using pixel scaling, like before.
Pixel scaling the window here gives us a height of 49 pixels. According to this article, the average height for windows is 60 inches. Pixel scaling the length and width of the Zero Pointer gives us a pixel count of 149.19 pixels and 100.49 pixels respectively. Scaling off of the window’s height gives us its actual dimensions which are 177.16 inches (Length) and 118.11 inches. (Width)
Applying the PSI (pounds per square inch) over the area Midoriya’s smash destroyed, we get a total force of 2.367 Million US tons of Force or 21.059 billion Newtons. Now, this has a lifting strength equivalent to
Class M. Impressive for the first time he's ever used his power, no?
But in order to convert this force into energy, we'll need to figure out how far the force traveled. Aka, how far the Zero Pointer's body got compressed.
Midoriya here is 234.45 pixels or 166 centimeters. The length the Zero Pointer's face must've compressed to is 250 pixels. Scaling this off of Midoriya gives us an actual height of approximately 2 meters.
Plugging this into our formula for joules (newtons*distance) we get 42.118 billion joules. Or the equivalent to 10 tons of TNT. Basically the equivalent to baseline
City Block level.
I'll let the comments decide on the authenticity of the methods I used though.
