Meaning & usage
Capital rho (Ρ) 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 rho form, encoded as U+03A1. Its uppercase identity matters in formulas: changing case can change the variable or quantity being represented.
capital rho occupies one Unicode code point. A similar-looking letter, punctuation mark or emoji is not necessarily interchangeable with Ρ in search, filenames or text processing.
