CraftCalc Tools

CraftCalc is a practical collection of calculators and planning tools designed to help you solve common in-game calculations quickly and clearly. Plan Nether travel, measure distances, organize storage, calculate XP and fuel needs, locate Java Edition slime chunks, and measure real mob farm performance — all with tools that work offline. TOOLS • Nether Converter Convert coordinates between the Overworld and the Nether in both directions. View practical block coordinates alongside precise results, with X/Z converted using the 8:1 ratio and Y kept unchanged. • Distance Calculator Measure the distance between two locations using Horizontal or 3D mode. See horizontal distance, full 3D distance and the X, Y and Z differences for builds, routes, tunnels and travel planning. • Stack Calculator Convert item quantities into full stacks and remaining items using stack sizes of 64, 16 or 1. See the inventory slots required and compare storage using Shulker Boxes, Single Chests and Double Chests, including the free slots left in the last container needed. • XP Calculator Calculate the XP required between two player levels, from the start of the current level to the start of the target level. See both the number of levels needed and the total XP required for enchanting, repairs and XP planning. • Fuel Calculator Calculate how much fuel is required to smelt a chosen number of items. Choose Coal, Charcoal, Block of Coal, Dried Kelp Block, Blaze Rod or Lava Bucket, then see the fuel needed, total smelting capacity and unused capacity. • Slime Chunk Checker — Java Edition Check whether a location belongs to a slime chunk using a Java Edition world seed. Enter block or chunk coordinates, see the chunk used for the calculation, and automatically find the nearest slime chunk with its chunk coordinates, block area and distance. • Mob Farm Rates Calculator Measure the performance of your own mob farm from a real sample instead of relying on preset estimates. Enter the sample duration and any measured values you have — mobs killed, drops collected or XP gained — to calculate hourly rates. When both mobs and drops are provided, CraftCalc also calculates the average drops per mob.
