Physics Symbols
Copy useful calculus, field, flux, constant, vector, angle, wavelength, and resistance symbols for physics notes.
This set keeps the operators and Greek symbols that frequently share the same physics equation on one practical page.

Accurate use
Technical and compatibility guide
Use this collection as a plain-text notation palette for variables, units, vectors, and formula fragments. It supplies characters, not a definition of the physical quantity in a particular equation.
| Character | Unicode | HTML | LaTeX |
|---|---|---|---|
| ΔGreek capital delta | U+0394 | Δ | \Delta |
| μGreek small mu | U+03BC | μ | \mu |
| ΩGreek capital omega | U+03A9 | Ω | \Omega |
Common mistakes
- Define symbols whose meaning changes by context: Δ can mean a finite change, while Ω can be a Greek letter or the ohm symbol.
- Do not confuse Greek μ (U+03BC) with the legacy micro sign µ (U+00B5) when consistent searching or data processing matters.
Word, Docs, Notion, and plain text
Word, Google Docs, and Notion accept these Unicode symbols, and plain text keeps the characters but not professional equation spacing. Use an equation editor for fractions, aligned derivations, or stacked indices.

Frequently asked questions
How do I copy these symbols?
Press any large symbol card or snippet. Quick Symbols copies it immediately and adds it to the copy tray, where you can combine several items.
Can I use these in Notion or Google Docs?
Yes. These are standard text characters, so you can paste them into Notion, Google Docs, email, notes, and most other text fields.
Do these work in Microsoft Word?
Yes. Paste them into Word like ordinary text. Their exact appearance can vary slightly with the selected font.
What is the difference between similar symbols?
The groups on this page explain the practical differences between the physics symbols shown here, including which forms fit common notes and equations.
