Coordinate Format Converter

Convert decimal degrees to degrees, minutes, seconds

About this calculator

The Coordinate Format Converter transforms GPS coordinates between decimal degrees (DD) and degrees, minutes, seconds (DMS) formats. Decimal degrees express location as single numbers like 40.7589°, while DMS format breaks coordinates into degrees, minutes, and seconds like 40°45'32". This tool is essential for surveyors, pilots, hikers, and GIS professionals who need to work with different coordinate systems across various mapping platforms and navigation equipment.

How to use

Enter your coordinates in decimal degrees format (e.g., 40.7589) into the input field. Click the convert button to instantly transform the decimal value into degrees, minutes, and seconds format. The result will display the equivalent DMS coordinates, making it easy to use across different mapping systems and GPS devices.

Frequently asked questions

What's the difference between decimal degrees and DMS format?

Decimal degrees use single numbers (40.7589°) while DMS breaks coordinates into degrees, minutes, and seconds (40°45'32"). Both represent the same location differently.

When should I use DMS instead of decimal degrees?

Use DMS for traditional navigation, surveying equipment, marine charts, and aviation maps. Many GPS devices and nautical applications prefer this format.

How accurate is the conversion between coordinate formats?

The conversion is mathematically precise with high accuracy. Minor rounding may occur at extreme decimal places, but results are suitable for all practical applications.
