For a thin rod of mass m (kg) and diameter D (meters) spinning about its center, formula is m*D^2/12. See the [http://en.wikipedia.org/wiki/List_of_moments_of_inertia Moments of inertia reference page] and [http://www.engineeringtoolbox.com/moment-inertia-torque-d_913.html list of conversion factors for different units for moment of inertia].) | For a thin rod of mass m (kg) and diameter D (meters) spinning about its center, the formula is m*D^2/12.
