Key Features & Capabilities

Instant bi-directional Overworld <-> Nether coordinate conversion (8:1 scale factor on X and Z axes, 1:1 on Y)
Calculates exact Chunk Coordinates: Chunk X, Chunk Z, and local offset (0 to 15) inside the chunk
Calculates Anvil MCA Region File name (e.g., r.0.-1.mca) for map backups and server trimming
3D Euclidean block distance and travel time calculator (walking, sprinting, minecart, Elytra, ice boat)
Height (Y-level) bounds validator for modern 1.18+ world generation (-64 to 320)

Step-by-Step Instructions

1Select the source dimension (Overworld or Nether).
2Input your X, Y, and Z coordinate values.
3View the synchronized destination coordinates, chunk ID, and region file.
4Optionally input a secondary target coordinate to calculate exact 3D travel distance and ETA.

Frequently Asked Questions

Why does Y coordinate stay the same between Overworld and Nether?

In Minecraft, the 8:1 spatial compression ratio only applies to horizontal axes (X and Z). The vertical Y axis remains at a 1:1 scale between dimensions.

How do chunk coordinates work in Minecraft?

Each chunk in Minecraft is 16x16 blocks horizontally. To find chunk coordinates from block coordinates, divide the block coordinate by 16 and round down (floor division).
