Minecraft Nether Portal Calculator
The Nether Portal Calculator converts coordinates between the Overworld and the Nether using Minecraft's 8:1 ratio. Enter a location, get its paired coordinate, and build both portals where they will actually link — no stray portals, no wandering the Nether to find your exit.
