My Document Properties Units are millimetres for length and kilograms for mass.

 

The Mass Properties dialog reports Moment of Inertia seemingly in units of kilograms*square millimetres.

 

What I rember from school is that moment of inertia is area in mm^2 x distance in mm x distance in mm.

 

Kilograms don't come into it, and the units should be mm^4.

 

How should I interpret the numbers in this report?
