Why can the height of a liquid column also represent pressure?

This is the simplest formula: P = density * gravitational acceleration * height

Because the height of the liquid column itself possesses a net pressure. In reality, much of the pressure is due to the net pressure generated by weight.

Since the formula for hydrostatic pressure is P=Hρg, and density and gravitational acceleration are constant and can be regarded as constants, there is a certain relationship between the height of the liquid and its pressure; hence, it is possible to represent pressure using the height of a liquid column.
