# Pressure may be defined as the linear momentum per unit volume. Is it correct? Check with dim. Analysis.

Dimensional formula of momentum = [ M¹ L¹ T⁻¹ ]

Dimensional formula of volume = [ M° L³ T° ]

momentum / volume = [ M¹ L⁻² T⁻¹ ] .........................(2)

(1) ≠ (2)

Pressure can not be defined as the linear momentum per unit volume.
