Steps to Find UTM Zone for an Address

Convert the Address to Latitude/Longitude

  • Use a geocoding service like:

  • Google Maps

  • OpenStreetMap

  • Example: "Paris, France" → Latitude: 48.8566, Longitude: 2.3522.

Formula for UTM Zone

INT((Longitude + 180)/6) + 1

  • Longitude is the decimal degree value of the location.

  • This gives you the zone number (1 to 60).

Example

Address

Latitude

Longitude

UTM Zone

Paris

48.8566

2.3522

=INT((2.3522+180)/6)+1 → 31

New York

40.7128

-74.0060

=INT((-74.0060+180)/6)+1 → 18

Sydney

-33.8688

151.2093

=INT((151.2093+180)/6)+1 → 56

Find Hemisphere

IF(Latitude>=0,"N","S")

So Paris → 31N, Sydney → 56S.
