Decimal Degrees ➝ Degrees Minutes Seconds
Convert decimal degrees into DMS format.
Decimal Degrees to Degrees Minutes Seconds (DMS) Converter
A Decimal Degrees to Degrees Minutes Seconds (DMS) Converter is an online tool that converts geographic coordinates expressed in decimal degrees into the more traditional degrees, minutes, and seconds format. This type of conversion is essential in navigation, mapping, surveying, GPS applications, and geospatial studies.
Using an online converter simplifies calculations, saves time, and ensures accuracy in mapping and location-based work.
Understanding Decimal Degrees and DMS
Decimal Degrees (DD)
Decimal degrees express latitude and longitude as a decimal fraction. For example, 40.7128° N, 74.0060° W represents New York City. Decimal degrees are easy to use in computer applications and GPS devices.
Degrees Minutes Seconds (DMS)
The DMS format breaks down a degree into 60 minutes, and each minute into 60 seconds. For example, the same New York City coordinate in DMS is: 40° 42′ 46.08″ N, 74° 0′ 21.6″ W. DMS is traditionally used in navigation, cartography, and legal land descriptions.
Why Convert Decimal Degrees to DMS?
Decimal degrees are convenient for calculations, but DMS is preferred for human-readable maps, GPS devices, surveying reports, and formal documents. Converting between these formats is essential for:
Navigation and GPS systems
Surveying and land measurement
Mapping and geospatial analysis
Marine and aviation charts
How the Decimal Degrees to DMS Converter Works
The converter applies a simple formula to transform decimal degrees into degrees, minutes, and seconds:
- The whole number of degrees is retained.
- Multiply the decimal fraction by 60 to get minutes.
- Take the decimal fraction of minutes and multiply by 60 to get seconds.
For example:
Decimal Degrees: 40.7128°
- Degrees: 40°
- Minutes: 0.7128 × 60 = 42.768 → 42′
- Seconds: 0.768 × 60 ≈ 46.08″
Result: 40° 42′ 46.08″
Decimal Degrees to DMS Conversion Formula
The conversion formula can be summarized as:
Degrees (°) = Integer part of decimal degrees
Minutes (′) = Integer part of (decimal degrees − degrees) × 60
Seconds (″) = (Decimal part of minutes) × 60
This formula works for both latitude and longitude.
Example Conversions
- Decimal Degrees: 74.0060° W
- Degrees: 74°
- Minutes: 0.0060 × 60 = 0.36′ → 0′
- Seconds: 0.36 × 60 = 21.6″
DMS: 74° 0′ 21.6″ W
- Decimal Degrees: 34.0522° N
- Degrees: 34°
- Minutes: 0.0522 × 60 = 3.132′ → 3′
- Seconds: 0.132 × 60 ≈ 7.92″
DMS: 34° 3′ 7.92″ N

Decimal Degrees to DMS Converter FAQs
Q: What is the difference between decimal degrees and DMS?
A: Decimal degrees express coordinates as a single number with decimals, while DMS breaks it into degrees, minutes, and seconds.
Q: Can I convert both latitude and longitude?
A: Yes, a DD to DMS converter works for both latitude and longitude values.
Q: Why not use only decimal degrees?
A: Decimal degrees are easier for computation, but DMS is preferred for readability, maps, and navigation charts.
