Formulas Used
Overworld -> Nether: xN = xO / 8, zN = zO / 8
Nether -> Overworld: xO = xN x 8, zO = zN x 8
Distance = sqrt((x2 - x1)^2 + (z2 - z1)^2)
Travel time = distance / speed
FAQ
Why do portals mislink sometimes?
Nearby portals can cross-link if converted coordinates are too close. Build target portals near exact converted values.
Should I round converted coordinates?
Yes. Round to practical integer coordinates when placing portal frames.
Can this plan large base networks?
Yes. Use route planning section to prioritize high-distance links first.

Minecraft Nether Portal Calculator FAQ
What is the Nether coordinate ratio?
The Nether uses an 8:1 ratio, so one block in the Nether equals eight blocks in the Overworld.
How do I link portals correctly?
Use the converter to align Overworld and Nether coordinates, then build portals at the matched values.
Does this help estimate travel savings?
Yes. Use the distance calculations to compare travel time with and without Nether hub routing.
