The Moment of Inertia of a Cylinder about the Central Axis calculator computes the moment of inertia of a solid circular cylinder of uniform density with radius a about the axis of the cylinder.

INSTRUCTIONS: Choose your preferred units and enter the following:

• (M) This is the mass of the cylinder.
• (a)  This is the radius of the cylinder.

Moment of Inertial: The calculator returns the moment of inertia (MoI) in kilogram-square meters.  However, this can be automatically converted to other moment of inertia units via the pull-down menu.
