Re: Gravity and pi



Of course it's a coincidence. It's purely a matter of the choice of the
system of units. Pi is dimensionless (same whether you measure things in
feet or meters or anything else). Acceleration g is 9.81 only in MKS
units, but quite different in cm or feet.

Hello!
Is it just a coincidence that the acceleration due to the
gravitational force on the surface of the earth is approximately pi
squared?
