In most systems, such as Google Maps, the degree symbol is omitted and thus the coordinates are expressed as ' 38.889722, -77.008889'.Ī DMS value is converted to decimal degrees using the formula (D + M/60 + S/3600). The decimal degree representation of the location of the United States Capitol is '38.889722°, -77.008889°'. The accuracy of the latitude part does not increase. Because the earth is a spheroid and not flat, the accuracy of the longitude part of the coordinates increases the further from the equator you get. A value in decimal degrees to 5 decimal places is accurate to 1.11 meter at the equator. The number of decimal places required for a particular accuracy at the equator is:Ī value in decimal degrees to an accuracy of 4 decimal places is accurate to 11.1 meters (+/- 5.55 m) at the equator. The equator is divided into 360 degrees of longitude, so each degree represents 111,319.9 metres or approximately 111 km. The radius of the semi major axis of the Earth at the equator is 6,378,160.0 meters resulting in a circumference of 40,075,161.2 metres. Latitude and longitude are usually expressed in that sequence, latitude before longitude.

Positive longitudes are east of Prime Meridian, negative longitudes are west of the Prime Meridian. Convert Coordinates provides the ability to convert and parse your coordinates in the most popular formats such as Decimal Degrees (DD), Degree Minutes Seconds (DMS), Degree Decimal Minutes (DDM), GeoRef, USNG, MGRS. Positive latitudes are north of the equator, negative latitudes are south of the equator. As with latitude and longitude, the values are bounded by ☙0° and ☑80° each. Decimal degrees are an alternative to using degrees, minutes, and seconds (DMS). Decimal degrees (DD) express latitude and longitude geographic coordinates as decimal fractions and are used in many Geographic Information Systems (GIS), web mapping applications such as Google Maps, and GPS devices.
