How it works

The beta symbol is β, Greek small letter beta, U+03B2. The 44 rows add the capital Β, the curled ϐ, the raised ᵝ and lowered ᵦ, maths styles such as 𝛽, strings such as β₁ and β⁻, and ß, which is not beta.

Read the full guide

Betas a formula uses

β₀ and β₁ are the coefficients of a regression, y = β₀ + β₁x₁ + ⋯, and β̂ with a hat is an estimate of one. 1−β is the power of a test. β⁻ decay gives off an electron and β⁺ decay a positron. Each is a ready row: the lowered digits are U+2080 to U+2082, the raised signs U+207A and U+207B, and the hat is the combining U+0302.

Tips

The ten maths styles such as 𝛽 are used only as mathematical symbols. Unicode defines each as β or Β in a named font.
In LaTeX, \beta works in maths mode with no package, and \hat{\beta} adds the hat of an estimate. The kernel has no \Beta.

Questions and answers

How do I type the beta symbol on a keyboard?

β has no Alt code and no Option key. On Windows, Alt+225 on the number pad gives ß, the German sharp s, which is a different letter. On a Mac with the U.S. layout, Option+S gives ß too. So copy β from this page.

What is the HTML code for beta?

β or β for β, and Β or Β for the capital. The curled ϐ has no name, so write ϐ or ϐ. ß is the sharp s, not beta.

Is ß the same as beta?

No. β is the second Greek letter, U+03B2. ß is the German sharp s, U+00DF, an s-s or s-z ligature. Code page 437 has ß in slot 225, and some PC fonts drew it as a beta. Their capitals differ too: Β and ẞ.

What does the beta symbol mean?

In statistics β is the probability of a type II error, so a test's power is 1−β, and it also names a regression slope. In physics it is a beta particle, an electron or positron. In finance beta measures portfolio risk.

About the letter, all checked 2026-09-19: https://en.wikipedia.org/wiki/Beta (second letter, value 2 in Greek numerals, said as v in Modern Greek with the sound b written mu pi, derived from Phoenician beth, Latin B and Cyrillic be and ve arose from it, the curled form inside a word in French typesetting, the capital drawn like a Latin B, the voiced bilabial fricative, a raised beta for a compressed vowel, type II error and regression slope, the sharp s as a common mistake, and the list of characters named beta including the Coptic, Ugaritic and squared katakana ones), https://en.wikipedia.org/wiki/Code_page_437 (225 is identified by IBM as the sharp s and is sometimes rendered in OEM fonts as a Greek small beta), https://en.wikipedia.org/wiki/Beta_particle (β− decay and β+ decay produce electrons and positrons; β+ decay is also called positron decay), https://en.wikipedia.org/wiki/Linear_regression (y = β0 + β1x1 + ⋯ + βpxp + ε; a hat on the estimate), https://en.wikipedia.org/wiki/Simple_linear_regression (slope β, estimated values with a hat), https://en.wikipedia.org/wiki/Power_%28statistics%29 (power is 1 − β, where β is the probability of a type II error), https://en.wikipedia.org/wiki/Alphabet (the word was made from alpha and beta), https://en.wikipedia.org/wiki/Gamma (third letter) and https://en.wikipedia.org/wiki/Coptic_script (second letter, Greek equivalent beta, numeric value 2). \beta and \hat are declared in fontdef.dtx, which has no \Beta. None of those sources has a macro for U+03D0, so that row carries none. What is listed: every character whose Unicode name holds the word beta, the sharp s and the Latin B that get mistaken for it, letters that came from it or that it came from, and this site's own ready-made strings. Left out: the other Greek letters, which have their own pages. The last group holds characters that one ordinary computer had no font for on the day this list was checked; your device may differ. U+1DE9 is one of them and is shown on a dotted circle, U+25CC. The Start here group, the made rows and the order are this site's own choice. All sources were checked on 2026-09-19.
