g in SI units is very close to pi^2.

And the weird thing is that it almost is not a coincidence! The meter was almost defined as a second pendulum (implying pi^2 is exactly g) but then the variability in g was considered to impractical.

So then they choose the first meter definition (1/4 circ. if the earth)... which is suspiciously close to what they wanted to define the meter with in the first place

Still off by a factor 1000. That's the kilometer.
