What is the Dimensional Formula of Moment of Inertia?

Moment of Inertia is defined as the product of mass and the square of the perpendicular distance to the specified axis of rotation.

Mathematically,

Moment of Inertia is defined as the product of mass and the square of radius of gyration

Moment of Inertia = Mass X (Radius of Gyration)²

Now we know
Dimensional Formula of Mass= (M¹L⁰T⁰)
Dimensional Formula of Radius of Gyration= (M⁰L¹T⁰)

(Radius of Gyration)²=M⁰ L² T⁰

Putting these values in above equation we get
Dimensional Formula of Moment of Inertia= M¹L²T⁰
SI unit of Moment of Inertia is kg m²
