Summary
Copy the empty set symbol (∅) and find the exact Unicode value, HTML entity, LaTeX command, or keyboard shortcut for your platform.
How it works
- Click the large empty set symbol to copy it to your clipboard.
- Or click any format in the list (Unicode, HTML entity, LaTeX, CSS escape) to copy that exact string.
- Use the shortcut table to type the symbol directly from your keyboard on Windows, Mac, or Linux.
- Paste the symbol anywhere: documents, spreadsheets, code, or chat.
Use cases
- Write set theory statements in math homework or proofs, such as A ∩ B = ∅.
- Insert the empty set symbol into a LaTeX document with \emptyset.
- Show that a set has no elements in a spec sheet or slide instead of typing "empty".
- Add the empty set symbol to code, CSS content, or HTML without breaking encoding.
- Learn the keyboard shortcut so you never need to look it up again.
- Copy the correct HTML entity for a web page instead of pasting a raw Unicode character.
