What are the units for moment of inertia?

I'm doing a physics problem, but I don't know the units for moment of inertia.

1. kilogram-square meters REMEMBER: rotational inertia formulas typically have m*r^2 in them, and no other quantity with units. m is in kilograms, r is in meters. You may want to somehow include radians in there, but you don't really need to. Radians work in elegant manners, such that you don't need them in the units for rotational inertia. Do realize, that if you've used angular acceleration or angular velocity to find rotational inertia, you MUST convert them in to units containing radians and seconds exclusively...no RPM or degrees per second. Hint: what is the definition of a radian? The angle produced by an arc-length of one radius wrapped around a circle.
