# What is Dimensional Formula of Pressure Gradient?

Posted in Dimensional Formulae | Email This Post |**Pressure Gradient** is defined as the change in pressure per unit distance. In other words pressure change over a unit distance is known as Pressure Gradient.

Mathematically,

**Pressure Gradient = Pressure / Distance.**

Dimensional Formula of Pressure = M^{1}L^{-1}T^{-2}

Dimensional Formula of Distance= M^{0}L^{1}T^{0}

Substituting the values in the given equation we get,

**Dimensional Formula of Pressure Gradient = M ^{1}L^{-2}T^{-2}**

**SI unit of Pressure Gradient is Nm**
