Textures with metrics for prototyping

I've seen a lot of those textures in various engines:

But i'm curious about... how can you correlate texture resolution with in-game metrics? I mean, how can you say that a 1024x1024 texture occupies exactly 1 m inside the game engine metric system?

By simply mapping it to a properly scaled object, like a 1m^3 cube or a 1m^2 plane.

You can either map it tri-planar, but generally you want to map it as mentioned.

There are also tools that let you scale UVs so they're of a given texel density (like 1024px per metre).
