You could use Proj4js, as follows.

Download Proj4JS from GitHub, using this link.

The following code will convert from UTM to longitude latitude

In this code, the UTM zone is 32, as should be obvious. The Easting is 539884, and the Northing is 4942158. The result is:

[9.502832656648073, 44.631671014204365] 

Which is to say 44.631671014204365N, 9.502832656648073E. Which I have verified is correct.

If you need other projections, you can find their strings here.
