The Greek letter π was first adopted for the number as an abbreviation of the Greek word for perimeter, or as an abbreviation for "perimeter/diameter", by William Jones in 1706. The constant is also known as Archimedes' Constant, after Archimedes of Syracuse who provided an approximation of the number, although this name for the constant is uncommon in modern English-speaking contexts. It was later popularized by Leonhard Euler in 1737.
