So, a Blog version of the calc me (and then Perp) did before.

So uh, Papyrus do the boning there





























There is a pretty big bone there because reasons.

Compared to the SOUL, the bone is about 15.5 times taller than the SOUL as shown here.

































Since I'm a lazy bastard, I'm going to copy paste the fix of my Calc done by ThePerpertual, thanks to him btw.

"https://en.wikipedia.org/wiki/Femur This says that a person's femur bone, I.e. the one you're scaling to, is on average 26.74% of someone's height. Now that I'm thinking on it, my own femur bone is a lot longer than 14 cm, so if we're to take this seriously...

Average Human Male (just assuming since Papyrus is himself male, plus what else have we to work with?) = 69.7 inches, about, last I checked. Which would mean:

69.7 X .2674 =18.63778 inches, or about 47.3 centimeters.

Now, finding the weight of a bone is hard, but based on some research I've done...

Thickness of Femur: 29/411 = 7.06%

0.473 m x .0706 = ~0.0334 m, or 3.34 cm

Which means that, given the density of hard bone equaling 1900 kg/cubic meter....

1900 X .473 X .0334 X .0334 = ~1.0026 kg. The extra mass on the head and lower extremity should be able to counterbalance any hollowness, dryness, marrow, etc., and I'm pretty sure that a little over 2.2 lbs. sounds reasonable, so here we go.

So, if we are to use this:

Big Bone Height: 0.57 m X 15.68 (times taller than it) = ~8.94 m, or 894 cm

Scaling to In Real Life Bones: 8.94 m / 0.473 m = 18.901 times taller than an IRL femur.

Cubed, is 6752.34 times more massive in each dimension...

6752.341 X 1.0026 = Just about 6769.9 kg."

Now for the speed of the bones. There is no way to accurately do it, but Papyrus is much stronger than Napstablook who has shown Relativistic+ feats, so let's have Low end be 0.5 and High end be 0.9 c.

High End: 565329804419176660000 Joules, Large Island Level

Low End: 87821942894830810000 Joules, Island Level

This averages out to 326575873657003735000, which is Island Level+

Soo, there it is I guess.
