How to Use and Format the Pi Symbol
The character π is Unicode U+03C0 GREEK SMALL LETTER PI. In mathematics it commonly denotes the constant equal to a circle’s circumference divided by its diameter, but it is also a Greek letter and can represent other quantities when a formula defines it that way.
Use lowercase π for the circle constant, keep it distinct from uppercase Π and the n-ary product symbol ∏, and use mathematical markup when subscripts, exponents, fractions, or other complex notation are involved. A coefficient is commonly written next to π, as in 2πr.
Use lowercase π for the circle constant and uppercase Π only when that different character is intended.
Do not replace π with the Latin letter p or with the product operator ∏.
Write coefficients next to π in standard mathematical forms such as 2π or 4πr².
Keep degree and radian notation distinct; π radians corresponds to 180°.
Use enough digits of π for the accuracy required by the calculation.
Use MathML, LaTeX, or an equation editor for complex expressions containing π.
Pi Symbol Examples

Common Pi Symbol Mistakes
- Do not confuse π (U+03C0 GREEK SMALL LETTER PI) with Π (U+03A0 GREEK CAPITAL LETTER PI).
- Do not confuse π with ∏ (U+220F N-ARY PRODUCT).
- Do not treat 22/7 as exactly equal to π; it is an approximation.
- Do not round π too early when a calculation requires greater precision.
- Do not mix degrees and radians; π radians equals 180 degrees.
- Do not replace π with the Latin letter p.
- Do not assume 3.14 is precise enough for every calculation.
- Do not use an image of π when searchable Unicode or mathematical markup is appropriate.
More About the Pi Symbol
The pi symbol π is a Unicode text character, not an image. Pi is the Greek letter π. In mathematics, it commonly represents the constant equal to a circle’s circumference divided by its diameter. Because it remains selectable text, it can be copied into documents, messages, spreadsheets, source code, usernames, captions, and other fields that support Unicode. Its appearance can change with the active font or operating system, while the stored character remains U+03C0 (GREEK SMALL LETTER PI).
Supporting searches such as “mathematics pi symbol”, “pi symbol copy paste”, and “symbol for pi in math” usually describe the same core task from different angles: identifying the correct character, copying it, or learning how to enter it with a keyboard. This page keeps those intents together so you do not need separate pages for small wording differences. Use the copy control for the fastest method, then check the platform rows when you need a repeatable shortcut on a specific device or app.
Queries such as “pi symbol text” and “pi symbol copy and paste” are covered by the keyboard, application, and character-code sections. The Windows and Mac instructions explain practical input methods, while the Microsoft Word and Google Docs rows cover document editing. Unicode, HTML, hexadecimal, and CSS values are listed separately so developers can insert the exact character without confusing it with a similar-looking mark.
Choose π when its documented meaning matches the surrounding text, and compare the related-symbol links below when another character may be more precise. Spacing and visual style can vary by context, so follow the style guide of the document or platform. For example: C = 2πr
