What is Dimensional Formula of Angular Velocity?

Angular Velocity is defined as change in angular displacement per unit time. Its formula is

Angular Velocity =Angular displacement/Time
Dimensional Formula of Angular displacement= M⁰L⁰T⁰ Divide it by Time T¹

So Dimensional Formula of Angular Velocity = M⁰L⁰T^-1
SI unit of Angular Velocity is rad s^-1
