Those are not the correct equations for converting x,y,z to latitude and longitude. The Earth is not a sphere; latitude is not a spherical measure.nicksauce said:

The equations to convert x,y,z coordinates to longitude and latitude are known as the Geodetic Equations. These equations involve a series of trigonometric calculations and are used to determine the precise location of a point on the Earth's surface.
Converting x,y,z coordinates to longitude and latitude is necessary because these two systems use different reference points and measurements. Longitude and latitude use the Earth's geographic poles and equator as reference points, while x,y,z coordinates use a Cartesian coordinate system based on a specific origin point. Converting between the two allows for more accurate location data.
The equations to convert x,y,z to longitude and latitude do not change based on the location on Earth. However, the values used for constants such as the Earth's radius and the location of the origin point may differ slightly depending on the reference ellipsoid being used. These ellipsoids are designed to best fit the shape of the Earth at different latitudes.
Yes, there are many online calculators and software programs available that can perform these conversions quickly and accurately. Some may even allow you to input your own reference ellipsoid and origin point values for more precise results.
While the equations for converting x,y,z to longitude and latitude are generally accurate, there may be some limitations. These equations assume a perfect spherical or ellipsoidal shape for the Earth, which is not completely accurate. Additionally, small discrepancies in the reference ellipsoid used or the origin point values may result in slightly different coordinates. However, for most practical applications, these equations provide precise enough results.
