About GPS Coordinate Systems

Latitude and Longitude can be represented in one of three different formats:


Coordinate System Example Latitude Example Longitude
Decimal Degrees 44.475°N 116.98194444444444°W
Degrees and Decimal Minutes 44°28.5'N 116°58.916666666667'W
Degrees, Minutes, Seconds 44°28'30"N 116°58'55"W

The form below offers conversion between the available formats.


GPS Coordinate Conversion

To use this form, fill in only one row of latitude and one row of longitude (i.e. use only one of the three formats described previously), and click on the Convert button below the form. Only the first latitude and first longitude entries will be converted. Moving your cursor over the field names will display a tool-tip that describes the format and limitations of the field value. Do not enter hemisphere information (i.e. N or W) or punctuation (i.e. °, ' or ") when entering data in the form. Both the latitude and longitude must be popluated in the form in order to enable the calculator to operate.
