Ever found yourself alt-tabbing to a calculator while trying to figure out how many stacks of diamonds you need for a trade? REI Search Bar Calculations Mod eliminates that hassle by embedding a fully functional calculator right inside the Roughly Enough Items search bar.

Key Features
- Search Bar Calculator — Type math expressions directly into the REI search bar for instant results. Supports addition, subtraction, multiplication, and division (+, -, *, /).
- Metric Prefix Support — Use shorthand like
1kor5minstead of typing out full numbers, making large calculations much faster. - Minecraft Stack Unit — Calculate using item stacks as a unit, so you can quickly convert between raw item counts and stack amounts during gameplay.
- Enchanted Item Shortcut — Use
eto represent enchanted item variants, where 1e equals 160 items — particularly handy for Hypixel SkyBlock-style economies. - /calc Command — Run calculations from anywhere using the
/calccommand, even outside of the REI interface. Works identically to the search bar calculator.
