UNESCO equation to the conversion of water pressure to depth is widely used to oceanographers around the world. However, the Leroy and Parthiot equation (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.
p = water pressure (in MPa, relative to atmospheric pressure).
lat = latitude of the point (in degrees).
D = number of area of applicability.
z = water depth (in m).
z = pre2depth(5,[30,45,60],0)
