The **Pressure to Water Depth **calculator converts input pressure (P) and density of water (ρ) into the approximated depth of water where the pressure would occur.

**INSTRUCTION**: Choose units and enter the following:

- (
**P**) This is the pressure - (
**ρ**) This is the density of water (default of 1025 kg/m³ for sea water)

**Depth of Water (D): **The calculator returns the depth of water that would create the pressure.

#### The Math / Science

The column of water above an object creates a pressure that increases with the depth. This calculator estimates the depth required to create the specified pressure. The formula for the depth of water associated with a pressure is:

d = p / (g•ρ)

where:

- d = depth of water at pressure
- g = acceleration due to gravity
- ρ = density of water.
