Calculating Pi: Find Reliable Measurments

[Dawguard]

Does anyone know the measurments of a perfect circle? I've been trying to calculate Pi on my own, but I can't find a reliable set of measurments to use. Everything I've found so far has been close, but starts to deviate from the real Pi around the tenth decimal place.

What is this calculation you are doing ? You know that there is no such thing as a perfect measurement, right ? A perfect circle is a mathematical object. Neither will you find one in the physical world, nor be able to measure anything about it to arbitrary accuracy.

As Gokul points out, you won't get a particularly good value for pi by physical measurement. You need to compute it via mathematics

Enjoy!

Hmmm...I had been using simple division, so I was looking for a diameter and circumfrence. I had thought a perfect circle could exist in theory, and the measurements known, but apparently not.
Thanks for the link though, it's a great site!
