Pressure-to-Depth and Depth-to-Pressure Calculator
This calculator determines the water depth to reach a given pressure or the pressure at a given depth. You can enter the depth or pressure input with most common units and it will be converted automatically. This calculator does not add air pressure at the surface – the results are relative to the surface pressure.
Pressure and Depth Output:
This calculator uses simple hydrostatic pressure equations. The pressure, \(P\) of a fluid at depth depends only on the density, \(\rho\), the acceleration of gravity, \(g\), and the depth or height of the fluid column, \(h\).\[P = \rho g h \]
The calculator uses the following values for these parameters:
