A full circle corresponds to an angle of 2π radians.

Peter Trueb, after 105 days of non-stop calculations emerged with 22,459,157,718,361 fully verified digits of pi. That is over 22 trillion digits!
Emma Haruka Iwao ran her computers from September 22, 2018 to January 21, 2019 to emerge with 31.415 trillion units.
Newton calculated 17 and 17 digits is enough for most applications.

More facts (not guesses):

Pi ( $π$ ) is the exact ratio of the circumference of a circle to its diameter.
Pi is a constant.
Pi is an irrational number.
Pi is a transcendental number.
Pi is a non-repeating number – no pattern has been identified using computer analysis within over twelve trillion places.
Pi is a never-ending number.
Pi within any equation makes the result irrational, never ending and never repeating.
Pi is a dimensionless constant. It is a mathematical constant.

Pi is the simplest, most commonly-used dimensionless constant.
Pi is the bridge between the finite and the infinite.
The sphere is the first manifestation of spacetime defined by primordial spheres. The Planck Length and Planck Time are approximations of the smallest units of both.
