Hi,

Can you give examples of:

input Google coordinate values
output UTM coordinates that you're getting (and what definition/parameters you are using)
what are the expected values

Based on what Cliff Mugnier wrote in his column on the United Arab Emirates, Dubai is not using a standard UTM zone but a local transverse Mercator zone so you would need to create a custom projected coordinate system.

The Dubai Local Transverse Mercator (DLTM) Grid is referenced to the WGS 84 ellipsoid, the Central Meridian λo = +55° 20’ E, and the False Easting = 500 km. The Northings are presumably measured from the Equator.

There are a number of converters online if you know your input system and what output system you want to convert to.
Here is one:
