ight i gotta make this quick cus this is incriminating information and the US government is probably gonna assassinate me. When they do assassinate me. but according to the us military, the atom bomb dropped in hiroshima was equivalent to 17,000 metric tons of TNT. The per cube weight of tnt is about 0.33 per cm^3. (Just a quick not3 that brent (twoayem)did all of these calculations and research so credit me). taking this number we can find out how much a 1 meter by meter by meter cube weighs. as you may already know a block in minecraft is 1m^3. so the weight of a minecraft block of tnt comes out to be 330,000 grams of tnt in a single block. now since there is 1,000,000 grams in a metric ton, we can figure out how many 330 thousand gram blocks we need to match that of the bomb dropped on hiroshima. since 17,000 metric tons is equivaent to 17,000,000 grams. taking 17 million divided by 330,000 will give us about 52. this means that 52 blocks of tnt in minecraft is equivalent to the atomic bomb dropped on hiroshima.
the nuclear bomb power to TNT is a conversion is blast strength, not physical size, so to do a real kind of minecraft comparison you would need to work out the comparison of minecraft tnt blast to real tnt, and then work the nuclear comparison out from that
not from saying real tnt is this weight and minecraft tnt is this weight
Minecraft TNT obviously ins't as powerful as real life TNT. In real life, it's a specific compound that requires a fairly extensive chemistry kit to make.
In Minecraft, it's made by slapping some sand and gunpowder together. Maybe creepers have some magical properties, but I doubt it since TNT explosions are tiny. I've blown up several stacks of TNT all at once and it doesn't compare to a nuke.
I'm not sure where you got your numbers from but I found a density of 1.65 grams per cubic centimeter for TNT, or 1.65 metric tons per cubic meter, and to get 17,000 tons you'd need about 10,303 blocks of TNT - a factor of 198 higher than the 52 you got.
Also, another factor complicating the comparison between real-life and Minecraft TNT is that individual explosions do not stack; even if you set them off all at once they would still be multiple individual explosions (it is a myth that you could destroy even bedrock with enough TNT; the only way to do this is to change the explosion power of a single block).
There is also a way to estimate how big an explosion would have to be to produce similar effects; I found a site that calculates the effects of explosions and for a 17 kiloton explosion the crater produced had a radius of 50 meters:
This is dependent on the composition of the ground in either case but such a crater isn't practically possible in Minecraft due to limitations on how explosions are produced; past 16 blocks they will break up into distinct rays, leaving behind an odd cubical crater which appears the same for higher powers (the game projects a 16x16 grid of rays along each face of a cube, past 16 blocks the spacing between rays will exceed 1 block):
In order to get a number this low I had to go well under 1 ton (again, it only reports in intervals of 10 meters; 0.00001 kilotons was reported as 0 and 0.00002 was 10. Both cases gave 10 meters as the radius for 3rd degree burns, while Minecraft TNT cases no damage past 8 meters). This suggests that Minecraft TNT is around 100 times weaker than real TNT, at least in this aspect (in real life the size of the crater is much smaller than the area where you'd get serious injuries; a 17 kiloton explosion produces 3rd degree burns up to 35.6 times the crater radius and lesser injuries would occur even further away, while in Minecraft it is only slightly more than the crater radius, at least up to the point where it stops producing a proper crater).
Either you are joking or you are serious in the case you are serious I suggest you see a psychiatrist I can recognize the sign of a psychosis I have a lot of knowledge in it anyone in or towards a psychosis may feel the government wants to harm them or other things like you're targeted or the center of the world so judgement just an advice and if you're joking well cool
