Meaning & usage
Capital upsilon (Υ) 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 upsilon form, encoded as U+03A5. Its uppercase identity matters in formulas: changing case can change the variable or quantity being represented.
capital upsilon occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with Υ in search, filenames or text processing.
