🌍 What Is DMS (Degrees, Minutes, Seconds)?

DMS stands for Degrees, Minutes, and Seconds, a format used to represent geographic coordinates like latitude and longitude. It’s commonly seen in GPS data, maps, navigation apps, and surveying.

For example:
41° 24' 12.2" N, 2° 10' 26.5" E (Barcelona)

In this format:

• Degrees (°) represent whole units

• Minutes (‘) represent 1/60 of a degree

• Seconds (“) represent 1/60 of a minute or 1/3600 of a degree

📐 Why Convert DMS to Decimal Degrees?

Decimal Degrees (DD) are the standard format for most digital applications, including:

• Google Maps

• GPS devices

• GIS software (like ArcGIS or QGIS)

• Online databases and APIs

Decimal format is easier for computers to read, store, and process.

❓ Frequently Asked Questions (FAQs)

1. What’s the difference between DMS and Decimal Degrees?

DMS breaks down degrees into minutes and seconds; Decimal Degrees is a single number. Both represent the same location but in different formats.

2. Why are South and West values negative?

In the decimal system, North and East are positive, South and West are negative to reflect their direction from the origin (Equator and Prime Meridian).

3. How do I convert Decimal Degrees back to DMS?

Reverse the formula:

• Degrees = integer part

• Minutes = integer of (decimal part × 60)

• Seconds = remaining decimal × 60
