The units of the area moment of inertia are derived directly from its defining integral, $I = \int r^2 dA$. The differential area element $dA$ has units of length squared (e.g., $m^2$).

Conditions: Lengths are measured in meters in the specific example.; The integral represents an area moment of inertia.
