Common Uses
| Field | Example | Meaning |
|---|---|---|
| Physics | Radioactive decay that emits a beta particle (electron or positron). | |
| Finance | Beta coefficient: a stock 20% more volatile than the market. | |
| Statistics | Probability of failing to reject a false null hypothesis. | |
| Math | The beta function, a special function related to the gamma function. | |
| Software | A pre-release version label, unrelated to the Greek letter itself. |

Quick answer
The lowercase beta symbol is β (U+03B2) and the capital is Β (U+0392). Click either one to copy it, or type it with the method for your app. Do not use the German ß as a stand-in, because it is a different letter.

Summary
Beta is the second Greek letter, written Β or β, and appears in math, physics, statistics, and finance. Copy either case or use its Unicode, HTML, and LaTeX code.
How it works
- Click the large beta symbol to copy it to your clipboard.
- Switch between uppercase (Β) and lowercase (β) with the toggle.
- Click any row in the formats list to copy that exact string: Unicode, HTML entity, or LaTeX.
- Paste the symbol anywhere: documents, spreadsheets, code, or chat.
Use cases
- Write beta radiation or particle physics notation like β-decay.
- Reference the beta coefficient in finance, the measure of a stock's volatility against the market.
- Insert beta into statistical formulas, such as regression coefficients or Type II error rate.
- Type Greek letters in a physics or engineering report without a special keyboard layout.
- Copy the correct LaTeX command (\beta) for a paper or lab report instead of typing it from memory.
- Add beta to a plan or version label (Beta Release, v2 beta) using the real Greek character.
