- dredmorbius 7y agoThe pressure is determined by the mass of the water column above you. If water were compressible (as air is), that mass would vary by depth, complicating calculations. As water compresses minimally, density is constant, and computing based on area and depth at 1000 kg/m^3 is sufficiently accurate.
