StackCalc Revived
StackCalc Revived is an updated version of the Fabric client mod originally created by TomB_134. This tool helps Minecraft players quickly perform calculations related to converting item quantities into stacks, shulker boxes, or double chests. The mod has been completely rewritten with improved code and includes several additional quality-of-life features.
How to Use
Open the chat, enter any number and add the suffix s (for example, 1234s), then press the TAB key. The system will automatically convert the item quantity into the corresponding number of stacks.

Suffixes sb for calculating shulker boxes and dc for double chests are also available.

Version 1.1 feature: You can change the stack size by adding -<stack size> after the suffix.
