How it works

The pi symbol is π, Greek small letter pi, U+03C0. The 46 rows add the capital Π, the variant ϖ, maths styles such as 𝜋, the product sign ∏ and formulas such as 2πr and πr², which copy as one string, superscript included.

Π the letter and ∏ the sign

Unicode has two capital pis. Π, U+03A0, is the Greek letter. ∏, U+220F, is the product sign, the one \prod prints in LaTeX and ∏ gives in HTML. Use the sign in a formula and the letter in Greek text. Gauss introduced the product notation in 1812.

Tips

Styled rows such as 𝜋 are made for maths. In Greek words they space badly beside ordinary letters, so Greek text wants the plain π.
ϖ looks like an omega under a bar, yet it is a pi: Greek pi symbol, \varpi in LaTeX and ϖ in HTML.
Pi Day is 14 March, 3/14 in month-first dates. Larry Shaw started it in 1988 at the Exploratorium in San Francisco. Hence the 🥧 row.

Questions and answers

How do I type the pi symbol on a keyboard?

On Windows, switch Num Lock on, hold Alt and type 227 on the number pad. On a Mac with the U.S. layout, press Option and P. In Word, type 03C0, then press Alt and X. On a phone, copy π from this page.

What is the HTML code for pi?

π is the small letter and Π the capital, so case is the whole difference. The numeric forms of π are π and π. The product sign is ∏, and the variant ϖ is ϖ or ϖ.

How do I write pi in LaTeX?

\pi prints π and \Pi the capital, in maths mode with no package. \varpi is the variant ϖ and \prod the product sign. The double-struck ℼ has no macro in standard LaTeX. The unicode-math package calls it \Bbbpi.

Who first used π for 3.14159?

William Jones, in 1706, in his Synopsis Palmariorum Matheseos. Leonhard Euler used it from 1736, and after his Introductio of 1748 it spread. π is the first letter of the Greek words for periphery and perimeter.

How this list was compiled: Names, and the code points they belong to, are checked against UnicodeData.txt, version 18.0.0 (https://www.unicode.org/Public/18.0.0/ucd/UnicodeData.txt), and printed in sentence case; its decomposition field is what says a maths alphabet character is U+03C0, U+03A0 or U+03D6 in a font. Other names for a character (omega pi, product sign, reduced Planck constant) are from NamesList.txt of the same version (https://www.unicode.org/Public/18.0.0/ucd/NamesList.txt); the version a character was added in is from DerivedAge.txt (https://www.unicode.org/Public/18.0.0/ucd/DerivedAge.txt), block names are from Blocks.txt, the Emoji property is from emoji-data.txt, and the years are from https://www.unicode.org/history/publicationdates.html. Alt codes are from the code page 437 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/PC/CP437.TXT) and the code page 1252 table (https://www.unicode.org/Public/MAPPINGS/VENDORS/MICSFT/WINDOWS/CP1252.TXT). Option keys were read from a U.S. keyboard layout; other layouts differ. HTML entity names are from https://html.spec.whatwg.org/entities.json, the HTML 4 name first where there is one, else the shortest. LaTeX macros are listed only when LaTeX's own fontdef.dtx (https://raw.githubusercontent.com/latex3/latex2e/develop/base/fontdef.dtx) or the amssymb and amsfonts sources (https://mirrors.ctan.org/fonts/amsfonts/source/) define them, matched to a code point through unicode-math-table.tex (https://github.com/latex3/unicode-math). What the letters are for, as the articles record it: the sixteenth letter, its Cyrillic, Coptic and Gothic descendants, the product notation and the variant pi with its name pomega and its use for the longitude of pericentre, https://en.wikipedia.org/wiki/Pi_%28letter%29; Gauss and the product sign in 1812, https://en.wikipedia.org/wiki/Table_of_mathematical_symbols_by_introduction_date; Pi Day on 14 March and Tau Day on 28 June, https://en.wikipedia.org/wiki/Pi_Day; the Zaghawa script, https://en.wikipedia.org/wiki/Zaghawa_alphabet. The last group holds characters that one ordinary computer had no font for on the day this list was checked; your device may differ. What is listed: every character Unicode names pi, the product and coproduct signs, letters of other alphabets that descend from pi, three characters often mistaken for it, the pie emoji, and this site's own formulas, which are two to four characters in a row with nothing between them. Left out: the other Greek letters (each has its own page) and the digits of pi. The Start here group, the made rows and the order are this site's own choice. All sources were checked on 2026-09-19.
