Difference between mass moment of inertia and second moment of area

[Shady99]

Hello i have known moment of inertia to be kg mm2 i.e. the product of mass and distance but i was looking at the euler buckling formula and it has moment of inertia in it which has units of mm4.whats the differnece between the two inertias.please help

Euler's buckling formula uses the second moment of area:

https://en.wikipedia.org/wiki/Second_moment_of_area

This article is about the geometrical property of an area, termed the second moment of area. For the moment of inertia dealing with the rotation of an object with mass, see mass moment of inertia.
