π (Pi) is a mathematical constant whose value is the ratio of any circle's circumference to its diameter in Euclidean space; this is the same value as the ratio of a circle's area to the square of its radius. It is approximately equal to 3.141593 in the usual decimal notation. Many formulae from mathematics, science, and engineering involve π, which is one of the most important mathematical and physical constants. Unlike many physical constants, pi is a dimensionless quantity, meaning that it is simply a number without physical units.
