python - Trying to convert latitude longitude values in UJIIndoorLoc dataset to degrees

I'm trying to convert the latitude and longitude values in UJIIndoorLoc dataset to degrees. The paper mentions that the data is in UTM from WGS84.

Here is an example of the values given:

• LATITUDE: 4864837.920500003


• LONGITUDE: -7360.497299999

Upon converting these I get values :

(lat: 43.76251700390833, lng: 2.6974029749144584)

But the result I should be getting should be near Universitat Jaume I in Spain (around 39.992845, -0.068439)

Can someone help me figure out the mapping please ?
