The absolute value of Block Bucks.

Nerd time! I'm going full Because Science on TerraTech to measure the value of Block Bucks in today's money. (I was inspired to do this by Austin5003 on the Discord Server.)
For this investigation I'm going to use SI units because they're the best

For this testing, I'll be using my lovely assistant here

The GSO Big Bertha is my anchor within the world of TerraTech for this investigation, because it is both very similar to something real, but also because it has a defined measurement already on it - the barrel has a diameter of 420mm according to the description. Obviously the real-world counterpart is the Krupp 42cm M-Gerät Kurze-MarineKanone.

From what I can see, the bore of the GSO Big Bertha's barrel is about 16/30 of a full block, so a full block is actually 30(420/16)mm = 787.5mm, not 1000mm as we had previously believed. (This makes the sizing of cabs even more awkward than we had thought :\ )

Assuming that one block was 1000mm, the dimensions of the Big Bertha aren't actually too far off the real Kurze-MarineKanone, but now that we know a block is actually 788mm we need to do some adjusting...

All of the next measurements assume I'm measuring the same areas on the GSO Big Bertha as the measurements for the Kurze-MarineKanone on Wikipedia were made.
The mantlet of the GSO Big Bertha is 4 blocks wide = 3152mm.
The height of the GSO Big Bertha, from fastenings to mantlet, is approximately 3.9 blocks - 3073.2mm.
The length of the GSO Big Bertha, from back to mantlet, is approximately 5 blocks = 3940mm

So our GSO Big Bertha is not quite the same size as the Kurze-MarineKanone...
Width: 3152:4700mm.
Height: 3073.2:4500mm.
Length: 3940:5040mm.

But we can find out what fraction it is the size of the Kurze-MarineKanone!
(3152+3073+3940)/3 = 3388.3
(4700+4500+5040)/3 = 4746.6

3388.3/4746.6 = 0.7138 = about 7/10, not too far off!

Now the mass quoted on Wikipedia for the Kurze-MarineKanone is 42,600kg, but the Kurze-MarineKanone is 140% the size of the GSO Big Bertha, so the mass of the GSO Big Bertha is actually 7.138(42,600/10) = 30407.88kg. I'll let you into a secret kiddo, blocks in TerraTech do actually have mass values, it's just that they make no sense in real life. The GSO Big Bertha has a mass of 52. (Which is actually close-ish to its actual volume.) Therefore, one mass = 30407.88/52 = 584.7669kg. (That means a GSO one block has a density of 811.4 kg/m^3. That's never going to float on water :D) (To get the masses, I'm using Exund's Advanced Building Mod, available on TTMM2)

Now my scales show that the masses of Fibron Chunks and Plumbia Ingots are equal which is important. These two chunks form the recipe of the GSO Two Block in an equal ratio. 1/4 of the mass of a GSO Two Block must equal the mass of a Plumbia Ingot = 292.3383kg. Also importantly is that Titania Ingots balance with 2 Plumbia Ingots, so they're 584.7669kg Titanite is the only resource that can easily be identified as one that we know about on earth - titanium, so we can calculate the price of 584.7669kg of titanium!

At the time of writing, a kilogramme of titanium costs 57.6729 US$ in the N. American market (data provided by, which makes 16,423.3408 US$ for a Titania Ingot... not cheap.
16,425.3408 US$ = 30 BB therefore 547.4447 US$ = 1 BB... according to this method of testing!

According to the steps I have done 1 Block Buck is equivalent (at the time of writing) to 547.45 US$, 491.30€ or 438.26£. (Conversion providedd by

DISCLAIMER: TerraTech is riddled with discrepancies :D Unless some magic has been done, 120 Titania Ingots would fit into a GeoCorp Titania Block, which only has a mass of 12 which would make Titania weigh 0.1 = 58.47669kg which my previous method staunchly disagrees with.

Let me know if I made a mistake or a bad assumption! This was really just for fun, and indeed I did have fun doing it :D
If anyone is doubtful about the quality of my testing equipment, I have appended the save game I used.
