About this Mod

Blocks to Stacks is a lightweight, client-side utility mod designed to handle block math directly in-game. When planning large builds or organizing storage rooms, tabbing out to a calculator breaks your focus. This mod solves that by instantly converting raw numbers into manageable Minecraft stacks.

Features & Usage

The mod adds a single, intuitive command to your chat:
/calc stacks <number-of-blocks> [<optional: stack size>]

Default Calculation: Type /calc stacks 300 and the mod will instantly tell you it equals 4 stacks and 44 blocks (defaulting to a standard 64-block stack).
Custom Stack Sizes: Type /calc stacks 150 16 to accurately calculate items like Ender Pearls, Snowballs, or Signs that max out at 16 per stack.
