I=mghT^2/4pie^2

[Kevinh]

What does the "g" stand for when computing moment of inertia, does it stand for gravity 9.80 m/s^2 or what. Thanks.

What is e here?

If this formule is about physical pendulum in gravitational field, then g is gravity (strength of gravitational field) in the vicinity of pendulum.

[Kevinh]

4pie^2 should be 4pi^2 I guess. This is an experiment where different objects are being placed on a knife edge through the object to test for experimental interia compared to calculated inertia.

Seems to me like a formula for period of physical pendulum. Then g is gravity indeed.
