I've decided to go through and calculate most of the feats Goku did in Dragon Ball for those that aren't directly covered, as I want to find which one best defines his strength at this current time. I'll start with the PIlaf saga feats and go from there. There are dozens of feats to cover, so I'll just include the most impressive ones (in my opinion and also stat wise). Also note, I have posted similar posts in the Comic Vine Dragon Ball Universe Standardized Feats list which you can find here: https://comicvine.gamespot.com/dragon-ball-universe/4015-56629/forums/dragonball-universe-standardised-feats-list-1847904/?page=19
Determing Goku's Height[]
First I'll cover Goku crushing a boulder during training. But before we measure it out, we need to determine how tall Goku is. This is done by comparing him to Yamcha and Puar. Puar seems to be the only character from Dragon Ball that hasn't changed in height, so by comparing her to Yamcha's standard 183 cm height in Dragon Ball Z, we can then determine everyone else's heights with these comparison shots: original-11134-111340612-6736262-measurement-20of-20kid-20goku-27s-20and-20puar-27s-20height.png
I am measuring from Yamcha's head to the center of his heels and the same for Goku. Yamcha's hair is thick and wavy, so I used a head stencil to get an idea of where it was. Puar was measured from the tip of her ears to the bottom of her torso, as her feet and tail aren't needed.According to these measurements, Goku's height comes in at 88.54 cm. So now that we know this information (and hopefully this height is accepted for all future measurements) I can measure the boulder that Goku rolled over and then lifted and squeezed. NOTE: Boulder crushing image is having trouble uploading, so I will put it in at another time.
Measuring the Boulder and Area of Failure[]
original-11134-111340612-6736269-measurement-20of-20kid-20goku-20lifting-20boulder.png This shot is the best angle we have to see the full length of the boulder, as the other shots are at an angle or post-destruction. Also, I am measuring just barely below Goku's heels to simulate his feet returning to normal. The difference is very minor if I'm off, so it should work fine. Now that we know the radius and diameter of the boulder, we can determine its volume, which we will need to see how heavy it is and the area of failure for the boulder. You'll see in the crushing that the rock was basically ripped in half, so the area of failure would be the cross section of the boulder. As you can see, the boulder is basically torn in half with little other destruction here. This means it was almost "cut" in this motion, making finding the area of failure, the place that was torn, far easier. We could also calculate the area from this image, but considering Goku's stance, the boulder having lost part of its mass and the angle of the shot, this isn't the ideal measurement image.
So the area of the boulder cross section will be the area of failure. So we just measure the area via the diameter: A = PI * radius^2. This gives us a result of 13,809.21 cm^2, or 1.38 m^2 to be simplified. We then compare to the shear strength of a common rock type that's brownish in color. I've chosen Shale, because it's in a dry area and matches the description pretty well and it one of the more common rock types. Shale has a shear strength from 3 to 30 MPa, or 305,914 to 3,059,148 kg/m^2. Some simple division of the area of failure to the shear strength will give us the force required to tear the rock in half: 422 to 4224 metric tons of force.
Relatively speaking, this is the strongest strength feat in the entire Pilaf saga and possibly the Dragon Ball era that doesn't involve the Oozaru. It even sticks out among Dragon Ball as a whole, given the range. However, we must take into context that this is a squeezing force, which operates in different ways than lifting or striking strength. Plus there's not really a direct metric to compare squeezing to any other form of strength, so we just have to take it as it is. Still, it gives us an idea of how powerful Goku is.
