What does β mean?

Beta (β, capital Β) is the second letter of the Greek alphabet. English speakers say “BAY-tuh” (US) or “BEE-tuh” (UK); in modern Greek it is pronounced “VEE-tah” and sounds like a v. Together with alpha it gave us the word “alphabet”.

The lowercase β is everywhere in technical writing. A beta version of software is feature-complete but still being tested by real users. In finance, beta (β) measures how much a stock moves compared with the market, so β = 1.5 means it tends to swing 50% more. Physicists write β for beta decay and beta particles (electrons or positrons), and statisticians use β for regression coefficients and for the probability of a Type II error.

β has no Windows alt code. The code Alt + 225 that many sites list actually types ß, the German sharp s, which only looks similar in some fonts.

Common uses

  • Software: “Now in β”, beta testers, open beta
  • Investing: a portfolio β of 0.8
  • Regression models: y = β₀ + β₁x
  • Nuclear physics: β⁻ and β⁺ decay
