The table below is a brief chronology of computed numerical values of, or bounds on, the mathematical constant pi (π). For more detailed explanations for some of these calculations, see Approximations of π. As of July 2024, π has been calculated to 202,112,290,000,000 (approximately 202 trillion) decimal digits.
where C is the circumference of a circle, d is the diameter, and r is the radius.More generally, = where L and w are, respectively, the perimeter and the width of any curve of constant width.
The constants listed here are known values of physical constants expressed in SI units; that is, physical quantities that are generally believed to be universal in nature and thus are independent of the unit system in which they are measured.

The U.S. NIPAs are prepared by the staff of the Directorate for National Economic Accounts within the BEA. The source data largely originates from public sources, such as government surveys and administrative data, and they are supplemented by data from private sources, such as data from trade associations (BEA 2008: 1–6).
Statue of Zu Chongzhi. Zu Chongzhi (Chinese: 祖沖之; 429 – 500 [1]), courtesy name Wenyuan (Chinese: 文遠), was a Chinese astronomer, inventor, mathematician, politician, and writer during the Liu Song and Southern Qi dynasties.
The number π (/ p aɪ / ⓘ; spelled out as "pi") is a mathematical constant, approximately equal to 3.14159, that is the ratio of a circle's circumference to its diameter. It appears in many formulae across mathematics and physics , and some of these formulae are commonly used for defining π , to avoid relying on the definition of the length ...
