The Underwater Pressure calculator compute the pressure exerted underwater by the water column directly overhead as a function of the density of the water (ρ), depth under water (d), and the acceleration due to gravity (g). WaterPressure.png

INSTRUCTIONS: Choose units and enter the following:

  • (ρ)  This is the density of the water (see below).
  • (d)  This is the depth under water.

Underwater Pressure (p): The calculator returns the pressure in pascals (Pa).  However, this can be automatically converted to other pressure units via the pull-down menu.
