Time to see if Undertale's gonna bomb!
Figuring out Frisk's SOUL size[]
Easy enough. The screen flashes a few times before a fight begins.
Frisk: 93px/137cm (It's accepted in our current calcs)
SOUL: 29px = (29/93)*137 = 42.72cm
Simple. I'll be using that as reference for other feats as well
Pyrope's explosion[]
SOUL: 15px/42,72cm
Explosion diameter: 206px = (206/15)*42.72 = 586.688cm or 5.86688m
Explosion radius: 2.93344m
They happen at the ground.
W = 2.93344^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 0.002 Tons of TNT (Wall level)
Unsurprising.
Metatton pulverizes a wall[]
Feat happens here. Original calc here. Just redoing the px
Frisk: 51px/137cm
Wall thickness: 6px = (6/51)*137 = 16.12cm
Each pixel is 2.69cm tall and wide. Or an area of 7.2361cm² per pixel.
There are about 6830px filling the wall... Trust me, I counted (by approximation, of course). There is a margin of error of about 5% here since I'm not going to fill every crack in this wall and went by approximation.
Area: 6830*7.2361cm² = 49422.563cm²
Volume: 49422.563*16.12 = 796691.71556cm³
Absolutely no fragments, so pulverization 214.35 (j/cc)
796691.71556*214.35 = 170770869.23 Joules or 0,041 Tons of TNT (Small Building level)
It's recalc time
Turns out Mettaton was slamming the door, and it made metal sounds. Given that this is a laboratory, it'd make sense that the wall are made out of steel. Mettaton punched it 8 times before pulverizing it, and steel pulverization is 1000 j/cc
796691.71556*1000*(1/8) = 99.6 Megajoules or 0,024 Tons of TNT (Small Building level)
Undyne's House Explode[]
It covers the entire screen, and the "black parts" of the screen are also part of the scenario as seen with Papyrus.
Frisk: 51px/137cm
Screen: 561px = (561/51)*137 = 1507cm or 15.07m
Radius = 7.535
Again, on the ground.
W = 7.535^3*((27136*1.37895+8649)^(1/2)/13568-93/13568)^2 = 0.0344 Tons of TNT (Small Building level)
Correction
It didn't destroy anything in particular, so I was told to use 5 PSI (0.344738 bars), and use the inside of the house for the diameter.
Frisk: 51px/137cm
Screen: 561px = (422/51)*137 = 1133.6cm or 11.336m
Radius = 5.668m
Again, on the ground.
W = 5.668^3*((27136*0.344738+8649)^(1/2)/13568-93/13568)^2 = 0.0016 Tons of TNT (Wall level)
Results[]
- Undyne's Oven: 0.0016 Tons of TNT (Wall level)
- Pyrope's Bombs: 0.002 Tons of TNT (Wall level)
- Metatton Pulverizes a Wall: 0.024 Tons of TNT (Small Building level)
