Convert decimal degrees (e.g. 48.8584) to degrees, minutes, seconds (48°51'30"N). Type your decimal latitude and longitude and copy the DMS result — free and in your browser.
Decimal degrees is compact and machine-friendly; DMS is what most printed maps, deeds and surveying instruments use.
To convert: the whole number is the degrees; multiply the remainder by 60 for minutes; multiply that remainder by 60 for seconds. The sign becomes N/S (latitude) or E/W (longitude).
48 = degrees. 0.8584 × 60 = 51.5 → 51 minutes. 0.5 × 60 = 30 seconds. So 48.8584° = 48°51'30". Positive latitude is N; negative is S.
Input can be decimal degrees (48.8584), DMS (48°51'30"N or 48 51 30 N), or DDM (48°51.5'N). The tool outputs DD, DMS, DDM, Web Mercator (EPSG:3857) and UTM at once.
Latitude runs −90 to 90 (N/S); longitude runs −180 to 180 (E/W). Mixing them up is the most common mistake — enter each in its own box.
The DD/DMS/DDM conversion is pure math and works offline. Web Mercator and UTM use a small projection library that downloads once and is then cached.
