0.0002926kg·m²
That's 2.9× as hard to spin as a small motor rotor, while a frisbee is 4.1× harder. Spun at 100 rad/s it would store about 1.463 J.
What it means
How hard is that to spin?
Moment of inertia depends on where the mass sits, not just how much there is. The same wheel about a different axis gives a different number.
The math
How to convert lb·in² to kg·m²
To convert pound square inches to kilogram square meters, multiply by 0.00029264.
