Blocks to Stacks
Blocks to Stacks converts a raw item count into full stacks and leftover items, so a player typing a number in chat gets the answer without a calculator.
What it does
Typing a command such as b2s followed by a number returns how many stacks and how many single items that quantity makes. The default calculation uses the standard 64-item stack, so a value of 300 reports 4 stacks and 44 left over. A second number after the count sets a custom stack size, which covers items that stack to 16, such as Ender Pearls, Snowballs or Signs.
The mod is aimed at planning large builds, organizing storage rooms and keeping a calculator from pulling focus away from the game. It needs Fabric API installed beside it. Blocks to Stacks is built for Minecraft 26.2 and is published for Fabric alone, in two game versions, 1.21.11 – 26.2. It is open source, released under the CC0 1.0 Universal license.
Key features
Stack calculation command
A single command returns the number of full stacks and the remainder for any item count typed in chat.
Default 64-item stacks
Without a second value, the calculation assumes the standard stack size of 64 items.
Custom stack sizes
An optional stack size lets the same command handle items that hold 16 or another size per stack.
Lightweight in-game math
Block math is done inside the game, so players can plan a build without leaving the world.
