It isn't equal to g even in SI units except at some very few spots on the surface of the earth. Change the units to any other system and it's not even roughly

It isn't equal to g even in SI units except at some very few spots on the surface of the earth. Change the units to any other system and it's not even roughly true. Edit: Now that i have read the article i see that it is no coincidence at all that it is close the pi squared. very interesting.
