Meaning & usage

Rho is the R of Greek — ρ measures density in physics and correlation in statistics; it looks like a Latin p but sounds like r. The capital form is Ρ and the lowercase is ρ; the lowercase is usually the one worth copying, because several Greek capitals look exactly like Latin letters.

Greek letters are the spare alphabet of science: when Latin letters run out, formulas reach for these. This page gives you both forms, every code, and the typing routes.

Frequently asked questions

How do I type ρ on a keyboard?

What is the capital of Rho?

The capital is Ρ (U+03A1) and the lowercase is ρ (U+03C1). Both are in the variants grid on this page.

Why does ρ sometimes show as a box or question mark?

The box (called tofu) means the device or font viewing it has no drawing for U+03C1 (Greek Small Letter Rho). The character itself is fine — try a different font or a newer device, or use one of the variants on this page.
