WGS84 Degrees Converter
Convert WGS84 coordinates between decimal degrees format (e.g., 13.6929°) and degrees, minutes, seconds format (e.g., 13° 41' 34.44").
Understanding WGS84 Coordinate Formats
Decimal Degrees Format
Decimal degrees express coordinates as a single number with decimal places. This is the most common format used in modern GPS devices, mapping software, and web applications.
Example: 13.6929° (latitude), -89.2182° (longitude)
Degrees, Minutes, Seconds (DMS) Format
DMS format breaks down coordinates into three components: degrees (°), minutes ('), and seconds ("). This traditional format is still widely used in surveying, navigation, and printed maps.
Example: 13° 41' 34.44" (latitude), 89° 13' 5.52" W (longitude)
Important Note
Both formats represent the exact same location on Earth. The difference is only in how the coordinate is written, not in the actual geographic position.
Converting Decimal Degrees to DMS
To convert decimal degrees to DMS format, follow these steps:
- The whole number part becomes the degrees
- Multiply the decimal part by 60 to get minutes (the whole number part)
- Multiply the remaining decimal from minutes by 60 to get seconds
Example: 13.6929° = 13° + (0.6929 × 60)' = 13° 41.574' = 13° 41' + (0.574 × 60)" = 13° 41' 34.44"
Converting DMS to Decimal Degrees
To convert DMS to decimal degrees, add the degrees, minutes divided by 60, and seconds divided by 3600. The formula is: Decimal Degrees = Degrees + (Minutes / 60) + (Seconds / 3600)
Example: 13° 41' 34.44" = 13 + (41 / 60) + (34.44 / 3600) = 13 + 0.6833 + 0.0096 = 13.6929°
When to Use Decimal Degrees
- Modern GPS devices and smartphones output coordinates in decimal degrees
- Easier to use in calculations and computer programs
- More compact and easier to read for most people
- Standard format for web mapping applications (Google Maps, etc.)
When to Use DMS Format
- Traditional format still used in professional surveying and land surveying
- Common in navigation and maritime applications
- More intuitive for understanding approximate location (e.g., "about 13 degrees, 41 minutes")
- Still found on printed maps and in historical documents
Summary
The choice between decimal degrees and DMS often depends on the context: use decimal degrees for modern digital applications and ease of use, and DMS for traditional surveying, navigation, or when working with printed maps. Both formats are equally accurate and represent the same location.
