I notice that depending on the enemy of the versus, standards of observation tend to change when there's been a lot of debate about a given universe.
While I recently tried to get the crux of firepower figures for WH40K, by going through some of the books the fans pick quotations from, when I realized that authors often sprout big numbers without being consistent within one book, be it about displayed firepower or the materials used for hulls and effects of internal explosions.

It was rather clear that the petals of flame quote, for example, tells a totally different story, and some heavy bombardment events could even easily be interpreted as kiloton or megaton firepower.
I'll probably return to this. While rereading it, I notice white_rabbit
posting a link to
an older thread.
His calc, basically, was as follows (about demolition charges):

The Imperiums explosives
" Each boxy device was fitted with six kilos of a high explosive compound developed specifically for the destruction of space hulks
The demolition charges had a wide blast area, and the destructive power unleashed within that area was an order of magnitude greater than almost any other explosive of similar size"
page 276 " Leviathan" Crucible of War anthology.
"as each bomb exploded it instantly vapourised an area one hundred metres in diameter with a huge reverberating thunderclap...the explosion from each demolition charge roared into a seething ball of plasma, burning with the heat of a star.
Volume of a 100 metre diameter sphere = 523598.78 cubic metres
Density of Iron:7860 kg/m3
Mass of 100 metre diameter sphere = 4115486410.8kg
Charges placed at "key structural locations" indicating likelyhood of lots of solid bulkheads and structures.
1% of mass = 41154864.108kg
Energy to vape a kg of iron 7.63 MJ/kg
assuming 25% solid iron mass 1028871602.7kg
energy to vape= 7850 TJ
Assuming 50% solid iron mass 2057743205.4kg
energy = 15700 TJ
Assuming 75% solid iron mass 3086614808.1
Energy = 23550 TJ
Just about 7.5 megatons if its a full sphere of iron.
Ignoring how efficient this weapon may or may not be, six kg for a megaton explosion is fairly impressive, I think the modern US equivalent is a thousand kg nuke warhead.
Basic meter of explosives, one ton releases 4184 MJ
Low end, a single kg of this releases 1300 TJ.
As long as I haven't fucked it up, We'll never shut Ralson up about nuclear shells now.
Interestingly, they have other none-specialised munitions of a lower order of magnitude in capability, as well as other explosives that are not specialised anti-spacehulk weapons.
So what quality of these explosives makes them better for taking out spacehulks ?
We observe the traditional ultra literal interpretation of about anything that can sound big.
First, the demolition charges are stated as being used for the destruction of space hulks. Although it would obviously lead them to go for the high ends with such a premise, let's consider that no matter how wanked up the number, it just doesn't get anywhere close to the high gigatons or teratons claimed to get through space hulks. There we get megatons doing the job, by taking the most absurd over the top understanding of vapourizing an area.
Of course, if you just think it's only about how far the fireball ranged, you *only* get 9-10 KT. If you understand vapourize as level, make flat most structures, it gets quite lower.
Now, some demolition charges tend to be hollow charges causing deflagrations, so they're less powerful. This would make the energy yields a tad superior, but not by absurd ends.
I'd also take Drachyench's claims in the thread you pointed to with a huge grain of salt.
I also like how none of the guys in that debate seem to realize that even a few months ago, there's been a couple of threads talking about the Death Star.
They completely ignore that Alderaan's mass was partially shoved into hyperspace instead of pushed outwards, by citing SWTC. We however know that the explosion is assymetrical and debris were slowed down, as a field formed at Alderaan's former coordinates. And that's, again, with a part of its mass spirited away into PlopLand.
There's also an unsourced quote about the Eclipse's superlaser that flies against anything else established about the weapon.
Of course, they think that a SW fleet can stand against a WH40K. That's old style SW Wank vs. High End WH40K.
This is typical post ICS debate.
Vehrec is basically doing very little work safe citing old sources. Hey, I think I'll drop a brick over there.
