The Greek Letter π and Gravity...

Consider the following formulae:
π2 ≈ 9.87
g ≈ 9.81 N/k
The constant g is the gravitational constant, for the force of gravity at the Earth's surface. 

The two numbers are very close.  I'd have dismissed this as pure coincidence, but in fact it is not.  Fascinating!
