Nether Portal & World Calculator

Convert Overworld & Nether coordinates (8:1), locate exact 16×16 chunk borders for farms, check 3D portal linking ranges, and calculate Shulker Box stacks.

1. Overworld ↔ Nether Portal Linker (8:1)

Type coordinates in either dimension to instantly calculate the exact linked portal position and obsidian needed.

Overworld Coordinates
Nether Coordinates (÷ 8)
Overworld Target: X: 800, Y: 64, Z: -1600
Nether Target: X: 100, Y: 64, Z: -200
Obsidian Required (2 Portals): 20 Minimal / 28 Full Corners

2. 16×16 Chunk Border Finder

Find the exact North-West and South-East corners of your current chunk so your redstone farms, mob grinders, and slime chunks never break across chunk boundaries.

Chunk Index: Chunk [50, -100]
NW Corner (Min X, Z): X: 800, Z: -1600
SE Corner (Max X, Z): X: 815, Z: -1585
Chunk Center (2x2): X: 807..808, Z: -1593..-1592

3. 3D Distance & Portal Conflict Checker

Enter two coordinates in the same dimension to measure exact 2D/3D block distance and check if two Nether Portals are far enough apart to link independently.

POINT A (X, Y, Z)
POINT B (X, Y, Z)
Horizontal (2D) Distance: 353.6 blocks
True 3D Distance: 353.6 blocks
Overworld Portal Separation: Safe (≥ 16 blocks)

4. Shulker Box & Stack Calculator

Building a megabase or perimeter? Convert any total block count into exact Shulker Boxes (1,728 items), Double Chests (3,456 items), Stacks, and Remainder items.

Breakdown: 7 Shulkers + 6 Stacks + 20 Items
Total Stacks: 195 Stacks + 20 Items
Double Chests Equivalent: 3.62 Double Chests

Frequently Asked Questions

How does Nether Portal 8:1 coordinate linking work?
In both Minecraft Bedrock and Java Edition, 1 block in the Nether equals 8 blocks in the Overworld along the X and Z axes. To link two portals accurately, divide your Overworld X and Z coordinates by 8 and build a portal at that exact spot in the Nether (keeping the Y height similar).
Why is the 16×16 Chunk Border Finder important for farms?
Minecraft loads and ticks the world in 16×16 block chunks. If a redstone contraption, iron farm, or sugar cane farm crosses an unloaded chunk border, pistons and hoppers can break. Building inside the NW and SE chunk corners shown above keeps your farm 100% chunk-aligned.
Does translating the website affect the numbers or coordinates?
Never! Every coordinate badge and number field is protected with notranslate so you can translate the page instructions into Hindi or any of the 10 supported languages with zero risk to your coordinates.
