Chunk Calculator

Turn block coordinates into chunk coordinates, block ranges, and region file names.
Works for Minecraft Java & Bedrock.

How to use this Minecraft chunk calculator:
Type your block X and block Z coordinates from in-game and this tool will instantly convert them into the correct chunk X/Z values using the standard 16×16 chunk grid used in Minecraft Java and Bedrock. It also shows the full block range for that chunk and the corresponding region file (r.x.z.mca). This is ideal for technical players, farm builders and mega base planners who want clean chunk-aligned builds, spawn-proofing, and accurate region file navigation.
