# The SI unit of moment of inertia is:

The SI unit of moment of inertia is kg.m2

Moment of inertia is defined as the ratio of net angular momentum of a system to its angular velocity around the principle of an axis.

The mathematical representation is given as:

 $I=\frac{L}{\omega }$

Where,

• I is the moment of inertia
• L is the angular momentum
• ω is the angular velocity
