How to use this calculator

Enter the ECEF X, Y and Z (metres).
Press Convert.
Read latitude, longitude and ellipsoidal height.

How it works

Converts ECEF Cartesian coordinates back to geodetic WGS84 latitude/longitude/height using Bowring's method.

Worked example

ECEF point. Returns the matching latitude, longitude and ellipsoidal height.

Frequently asked questions

Is the height ellipsoidal or above sea level?

Ellipsoidal (above the WGS84 ellipsoid). Use the orthometric-height converter to get height above mean sea level.
