ORECALC
Coordinate, trade & XP tools for Minecraft.
Three fast tools for questions that come up in almost every world: where a portal actually links, what a trade will really cost after discounts, and how much XP is left before the next level. Everything runs in your browser — nothing is uploaded or saved.
Convert Overworld coordinates to Nether coordinates (and back) with the 8:1 ratio.
See the final emerald price after zombie-cure discounts and Hero of the Village.
Find the exact raw XP needed to reach a target level, plus an estimated mob-kill count.
OreCalc is an independent, ad-supported set of reference tools for Minecraft: Java Edition survival mechanics. It isn't a mod, a server, or a Mojang product — just three calculators built to answer a question quickly and get out of your way. If something looks off, the "How this is calculated" section on each tool explains the exact formula used.
