Meaning & usage

Capital psi (Ψ) is a Greek letter used in writing and scientific notation.

Greek letters often label angles, constants or variables; uppercase and lowercase forms can represent different quantities.

This is the capital psi form, encoded as U+03A8. Its uppercase identity matters in formulas: changing case can change the variable or quantity being represented.

capital psi occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with Ψ in search, filenames or text processing.

How to type capital psi

Windows
Use Win + . for the emoji and symbol panel, or Character Map for supported fonts. In Microsoft Word, enter each hexadecimal code (3A8) and press Alt + X. There is no universal decimal Alt code for this character; legacy Alt codes depend on the code page.
Mac
Open Character Viewer with Control + Command + Space and search for capital psi. With the Unicode Hex Input keyboard enabled, hold Option and enter the UTF-16 units shown above. Standard Option shortcuts do not cover every Unicode symbol.
Linux
In compatible GTK applications, press Ctrl + Shift + U, enter 3A8, then Enter. Enter each code point separately for sequences. Other desktops or apps may require their character picker.
iPhone & Android
Look for capital psi in your emoji keyboard if available, or copy it here and paste. Save frequently used symbols as a text replacement or keyboard shortcut; availability varies by keyboard.
