Each node in the standard cube form has an exact size of 1×1×1. Expressed in nodebox coordinates, the cube fills the room from -0.5 to 0.5 in all 3 dimensions. I guess this means your starter cube in Blender is also your standard Minetest cube. :-)
The length is without a “real” unit by default, as the engine does not dictate nor specify one.
However, in Minetest Game the node length is generally understood to be 1 metre. But this is semi-official and not really a strict standard, more meant as a guideline for design purposes.
Other subgames might differ, but the 1 metre guideline is a safe bet in most of the cases.
But since Mintest is an engine, subgames are of course free to pretend that a node length is whatever they want. For a subgame where you play as a small rodent, it might sense for the subgame author to specify that the node length represents 1cm. But remember, this unit stuff is all just convention; it does not come from the engine.
Oh, by the way: If you want to create an entity/object which is just a cube (of any size), you do NOT need a model, there is a simpler way for that. Please re-read lua_api.txt.
I'm creating
MineClone 2, a Minecraft clone for Minetest.
I made the
Help modpack, adding in-game help to Minetest.
