Calculite

A standard calculator for doing simple maths in Obsidian, like adding up shopping lists, subtracting from countdowns, multiplying your gym reps, or dividing up averages. More convenient than switching to your system calculator, especially on mobile!

Supports any version of Obsidian all the way back to 0.13.30.

⤿ Desktop users can toggle a floating calculator that works anywhere on your computer.

How to use

Calculite works like most other desktop calculators. There's no back & forward history, but copy & paste is supported, and the plugin will remember your current equation even if you close and relaunch Obsidian, as long as you don't close the calculator tab.

There are four different ways to open the calculator:

1. The ribbon icon
2. The Show calculator command
3. The Toggle between sidebars command
4. The Toggle floating calculator command

You can use commands by opening the command palette. Show calculator opens a calculator tab (or finds an existing tab) and the Toggle commands switch the calculator between different positions.
