Calculate the pressure exerted by a column of fluid at a given depth.
Hydrostatic pressure depends only on depth, density and gravity — not on the shape or volume of the container. In water, roughly every 10 metres of depth adds one atmosphere. Because pressure depends on depth alone, a narrow tall pipe exerts the same pressure at its base as a wide tank of the same height.

This calculator takes 4 inputs: Depth below the surface, Fluid density, Atmospheric pressure at the surface, Gravitational acceleration. The pre-filled defaults are a realistic starting point — replace them with figures from your own environment for a result you can act on.
