To convert DMS to UTM: first convert DMS to Decimal Degrees (DD = D + M/60 + S/3600), then apply the Transverse Mercator projection formula to get UTM zone, easting, and northing.

How to Convert DMS to UTM: Step by Step
- 1 Convert DMS to DD using DD = D + M/60 + S/3600.
- 2 Determine UTM zone number from longitude.
- 3 Apply Transverse Mercator projection formula.
- 4 Add false easting (500,000m) and false northing if southern hemisphere.
Worked Example
Input
47°36'22"N 122°19'55"W
Latitude conversion:
47 + 36/60 + 22/3600 = 47.6061°
Longitude conversion:
122 + 19/60 + 55/3600 = 122.3319°W → UTM zone 10
Result:
10T 550254 5272543
Why Convert DMS to UTM?
USGS maps and older GPS devices show DMS, while surveyors and topo map users need UTM.
Common Mistakes to Avoid
- ✕ Skipping the intermediate DD conversion
- ✕ Using wrong sign for W longitude
