Pi (3.1415926535...) is the ratio of a circle's circumference to its diameter. (SG1: "Thor's Chariot") (ATL: "Tabula Rasa")

Dr. McKay knows Pi in at least 12 decimal places and was easily able to remember then on the first day he was diagnosed with an ailment known as Second Childhood. However, after only two weeks, he barely remembered it in just two decimal places. (ATL: "The Shrine")
