What is Dimensional Formula of Velocity Gradient?

Velocity Gradient is defined as rate of change in velocity per unit of distance.

Mathematically,
Velocity Gradient= velocity/distance.

Dimensional Formula of velocity= M⁰L¹T^-1

Putting these values in above equation we get,
Dimensional Formula of Velocity Gradient = M⁰L⁰T^-1
SI unit of Velocity Gradient is s^-1
