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)
