Understanding the Dimensional Formula of Pressure

The dimensional formula of pressure is derived from its definition. Pressure is defined as force per unit area. The formula for pressure (P) is:

P = F / A

Where:
P = Pressure
F = Force
A = Area

The dimensional formula for force (F) is [M L T^-2] and for area (A) is [L²]. Therefore, the dimensional formula of pressure is:

[M L T^-2] / [L²] = [M L^-1 T^-2]

So, the dimensional formula of pressure is [M L^-1 T^-2].
