Welcome to our calculator for moment of inertia for a solid circular section. Enter the diameter (**D**) of your section below, and see the results in the output section below.

This tool calculates **Ixx** and **Iyy** about the centroidal axis.

The moment of inertia of a solid circular section can be calculated using the equations shown to the right. **D** represents the section's diameter

Enter your inputs, and see outputs for **Ixx** and **Iyy** and section dimensions below!
