We prepared the radius of the gyration calculator here. So, you can use this calculator to easily calculate the radius of gyrations of objects. Because you will need this value in different kinds of mechanical calculations.

## What is the Radius of Gyration?

Firstly, we calculate the radius of gyration for cross-sections of 3D bodies or features. For each cross-section of bodies, the radius of gyration is also changed. The radius of gyration is generally used for buckling calculations of columns. The formula of the radius of gyration;

r is the radius of gyration of the cross-section. ‘I’ is the inertia moment of the cross-section and A is the area of the cross-section. Also, some cross-sections can have multiple cross-sectional inertias. When you calculate the radius of gyration, it must be the minimum value of that cross-section.

## How to Use Radius of Gyration Calculator?

Secondly, the use of the radius of the gyration calculator is very easy as you see above. Also, you just need to enter the I value in which the default unit is mm^4. Enter the area which is A as shown by the green arrow above that mm^2 can be the default unit for it.

Click on the ‘Calculate!’ button to calculate the radius of gyration in an mm unit. If you want to do this calculation again, click on the ‘Reset’ button as shown by the blue arrow above.
