Meaning & usage
α leads the Greek alphabet, which is why 'alpha' means the first or the leader everywhere: alpha males, alpha versions of software, the alpha star in a constellation. In physics α is the fine-structure constant and an alpha particle; in maths it often names an angle; in finance it measures performance above the market. Its capital form Α is identical to a Latin A, so the lowercase α is the one worth copying.
Examples in use
- Angle α = 35°
- The software is still in α testing
- Alpha Centauri — the system's brightest star

Frequently asked questions
How do I type α on a keyboard?
There is no standard Alt code or key for α. Copy it from this page; in Word, type 03B1 then press Alt+X.
Why does 'alpha' mean 'first'?
Alpha is the first letter of the Greek alphabet — the source of the phrase 'the alpha and omega', the beginning and the end.
Why does α sometimes show as a box or question mark?
The box (called tofu) means the device or font viewing it has no drawing for U+03B1 (Greek Small Letter Alpha). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.
Is the Alpha Symbol free to use?
Yes. α is a standard Unicode text character published in the Unicode Character Database. You may use it in personal and commercial documents, designs and products without permission or payment.
