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").

Degrees Format Converter
Convert coordinates between decimal degrees and DMS (Degrees, Minutes, Seconds) format.

Understanding WGS84 Coordinate Formats

What is the Difference Between Decimal Degrees and DMS?

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.

How to Convert Between the Two Formats

Converting Decimal Degrees to DMS

To convert decimal degrees to DMS format, follow these steps:

  1. The whole number part becomes the degrees
  2. Multiply the decimal part by 60 to get minutes (the whole number part)
  3. 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°

Why Do People Use Different Formats?

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  • Still found on printed maps and in historical documents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.
