The most accurate value of pi is 50,000,000,000,000 digits, and was achieved by Timothy Mullican (USA) in Huntsville, Alabama, USA, on 29 January 2020.
Timothy used the computer program y-cruncher to calculate 50 trillion digits of Pi using the Chudnovsky algorithm. The computation took over 8 months in total. He attempted this record to test the limits of his hardware and, during the process of attempting the record, Timothy founded a non-profit organization called the North Alabama Charitable Computing, which repurposes enterprise-grade compute and storage equipment for STEM research. Timothy plans to donate the server and hard drives used in the attempt to provide scientists and various research projects with computing power.
