What is DMS format?
DMS (Degrees, Minutes, Seconds) is a coordinate format that expresses latitude and longitude using degrees (°), minutes ('), and seconds (") with directional indicators (N/S for latitude, E/W for longitude). For example: 40° 42' 46" N, 74° 0' 21" W.
How accurate are the conversions?
Our converter provides high precision with seconds calculated to 3 decimal places, ensuring accuracy suitable for professional navigation, surveying, and scientific applications.
What is decimal degrees format?
Decimal degrees format expresses coordinates as decimal numbers, where positive values represent North/East and negative values represent South/West. For example: 40.713056, -74.005833.
How do I use the interactive map?
Click anywhere on the map to automatically populate the DMS coordinate fields with that location's coordinates. The map also displays your converted coordinates as a marker for visual verification.
