The current record for the number of digits of π stands at 314 trillion, computed in December 2025 by engineers at StorageView Lab.

Hardware: Dell PowerEdge R7725 with dual AMD EPYC 192-Core CPUs
Storage: Forty 61.44TB Micron 6550 Ion SSDs
Software: y-cruncher
Algorithms: Chudnovsky and Ramanujan
Run time: uninterrupted 110 days. That's an avg of over 33 million digits per second.

Over 75 years after Ramanujan developed the equation for π, the Chudnovsky brothers published this formula, which produces about 14 digits of π per term, more than 2x that of Ramanujan's formula.

There's some sorcery in these numbers.

This remarkable equation for π by Indian mathematician Srinivasa Ramanujan, developed around 1910-1914, is an infinite series with some curious numbers and an interesting property. The first k terms of the sum give π with ~8*k decimal digits.

E.g., the 1st term gives π = 3.141592 73001..., which is accurate to 6 decimal places.

Using 2 terms, we get π = 3.141592 653589793 87808..., which is accurate to 15 decimal places.

NASA uses a value of π = 3.141592653589793 with 15 decimal digits for interplanetary navigation.

Calculating the circumference of the circle with radius = 32 billion km, slightly larger than the distance of the Voyager 1 spacecraft, and π with 15 digits, gives an error of just 1.5 cm.

Calculating the circumference of the Universe with radius = 46 billion light years, with an accuracy equal to the diameter of a hydrogen atom, requires 37 decimal digits.
