Dimensional formula of pressure

Pressure
[M L−1 T−2]
Written in full: [M¹ L⁻¹ T⁻² A⁰ K⁰]

How to derive it

Pressure = Force ÷ Area

Put in the dimensions of each part: [MLT⁻²] ÷ [L²] = [M L⁻¹ T⁻²].

SI unit

The SI unit of pressure is pascal (Pa).

Same dimensions as pressure

These quantities have exactly the same dimensions, a favourite trick in JEE and NEET "which pair has the same dimensions" questions:
