Depth to Pressure Calculator
Calculator
This calculator uses simple hydrostatic pressure equations. The pressure, P, of a fluid at depth depends only on the density, ρ, the acceleration of gravity, g, and the depth or height of the fluid column, h.
P = ρgh
The calculator uses the following values for these parameters:
- ρfresh = 997.0474 kg/m³ (for freshwater)
- ρsalt = 1023.6 kg/m³ (for saltwater)
- g = 9.80665 m/s²
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.
