However, for high-precision surveying work - be aware that the two systems deviates more than half a meter.

Note that the World Geodetic System WGS84 and the European Reference System ETRS89 are virtually identical and that coordinate transformation between the two systems in practical navigation is unnecessary.

The east coordinate is the distance from the central median. The UTM north coordinate is the projected distance from equator for all zones. The units for both east and north coordinates are meters. Each zone is based on a specifically defined secant Transverse Mercator projection. The UTM system is not a single map projection but instead series of sixty zones. In the UTM coordinate system a grid is used to specify locations on the surface of the Earth.
