The symbol used by mathematicians to represent the ratio of a circle's circumference to its diameter is the lowercase Greek letter Ï, sometimes spelled out as pi, and derived from the first letter of the Greek word perimetros, meaning circumference. In English, Ï is pronounced as pie (/paÉª/, paÉª).
Pi is the English spelling of the sixteenth letter of the Greek alphabet. This means that the outside measurement of a circle is a little more than three times its width, a ratio that is one of the most important constants in mathematics.
