On: The Sanskrit verse for the value of pi

[hzay]

I don't think you can calculate the circumference of the Earth to within a few inches that easily because earth's topology isn't perfectly smooth. It has ups and downs all over.

[fizx → hzay]

And is significantly bulgy around the equator due to rotation. Calling BS.

[philhippus → fizx]

Not BS, take the equator as the circumference and a weighted average between sea level and the highest point on that line for the constant circular path and you'll have a measurement relative to pi.

[auctiontheory → hzay]

Right. It is undefined.
