Typical Use Cases
Geographic coordinates are essential for specifying exact locations on Earth. However, different systems and formats are used across various applications and disciplines. This converter helps bridge these differences by allowing easy conversion between the two most common formats.
Decimal degrees (DD) are commonly used in digital mapping applications, GPS devices, and geographic information systems because they're easier to work with computationally. The degrees, minutes, seconds (DMS) format is the traditional way of representing coordinates on navigational charts, maps, and in many official documents and publications. Being able to convert between these formats is useful for navigation, mapping projects, geocaching, astronomy, and when working with location data from different sources.
Formula
Decimal Degrees to DMS:
DD = d + (m / 60) + (s / 3600)
DMS to Decimal Degrees:
d° m' s" = d + (m/60) + (s/3600)
- d: Degrees (whole number part of coordinate)
- m: Minutes (1/60 of a degree)
- s: Seconds (1/60 of a minute or 1/3600 of a degree)
- DD: The decimal degree value
- Direction: N/S for latitude, E/W for longitude - affects sign of the value
