UNESCO equation to the conversion of water pressure to depth is widely used to oceanographers around the world. However, the Leroy and Parthiot equation (

) considers corrective terms, in function of various areas of the world; with this term, the water depth value reaches a better accuracy.

Inputs:

p = water pressure (in MPa, relative to atmospheric pressure).

lat = latitude of the point (in degrees).

D = number of area of applicability.

Output:

z = water depth (in m).

Example:

z = pre2depth(5,[30,45,60],0)
