My 7 year old has started playing Minecraft and I'm curious as to how big in "real" measurements a block is. Would be fun to make some scale models…
It has been well established that the length of the sides of one solid block in Minecraft is 1m, making its volume 1m³. This is supported by Gamepedia.
The height of the player is 1.8 blocks, thus 1.80 meters.
The wiki also mentions voxels, which is kind of like a 3D pixel. Because the blocks use 16x16 textures, you could consider a voxel to be 6.25 cm on a side and to have a volume of 244 cm³.
According to the Minecraft wiki, Minecraft uses the metric system. Each block is 1 cubic meter.
I was thinking about the 1 cubic meter, and if you take the avatars hight yes is 1.8 meters but if you take his with (shoulder to shoulder) is 1 meter and no one has 1 meter with shoulders. So I took the drowing aproche, to make a even propotional human body you can messure the head and mutiply by 8 and you can determen the ideal hight.
Example : my head mesurment is 24 cm (9.6 inches) so my ideal hight should be 192 cm (76.8 inches) but my hight is 168 cm or 7 times my head size. If I take these aproche and put it in minecraft, the minecraft avatars hight is only 3.5 heads, were you can draw the conclusion that hes ultra short or he has the proportions of a child.
If you agree with me that the avatar is very short/a child (to take my mesurments of 24 cm for his head, his body is 84 cm) and the conclusion can be taken that every cube is aprox (46 cm) 0.5 meters per side, 0.125 m3, or you need 4 cubes to make 1 m2, if you need to make a cubic meter you need to 8 minecraft cubes.
This is my take on it. (sorry for my bad english, i tried to make some corrections)
Well, Minecraft is 125 times bigger than Earth, so 1 block would be 1/2 the height of 1 full-grown man cubed times 125. Since the average height of a full-grown man is 70 inches, divide that by 2 (35 inches), cube that (42875 cubic inches), despite the fact that Minecraft has cubes, and multiply 42875 cubic inches by 125, which is about 5.4 million cubic inches (exactly 5359375 cubic inches)! Also, this is exact IRL (in real life) measurements. The volume of the planet of Minecraft is 2.6*(10^14) cubic miles, which isn't even as big as Jupiter, despite that the volume is 3.43*(10^14) cubic miles! Woah!!
