COORDINATE NOTATION WORKSPACE

Coordinates Converter

Convert latitude and longitude among decimal degrees, degrees-decimal-minutes, and degrees-minutes-seconds notation.

Reviewed reference factorsValues stay in this browser tabLatitude -90 to 90; longitude -180 to 180; notation changes only.

Conversion input

Rewrite one coordinate pair in three common formats

Choose the format you are entering, supply latitude and longitude in that order, then compare all three notations before copying or exporting.

Input coordinate format

Select DD, DDM, or DMS to match the notation you will enter.

Latitude

Latitude comes first. Use -90 to 90 in decimal degrees, or N/S with non-negative degrees in DDM or DMS.

Longitude

Longitude comes second. Use -180 to 180 in decimal degrees, or E/W with non-negative degrees in DDM or DMS.

Displayed precision

Choose the maximum decimal places shown. This does not increase source accuracy.

Conversion runs locally after the active reference catalogue loads.

Load the New Delhi example or enter a coordinate pair to see DD, DDM, and DMS notation together.

What this tool delivers

Notation conversion without location claims

The same numeric position is reformatted locally; the workspace does not geocode, map, or transform a geodetic datum.

What it converts

Parses one latitude-longitude pair in DD, DDM, or DMS and writes equivalent notation in all three formats.

What you provide

The input notation, latitude first, longitude second, valid minute and second values, and consistent signs or hemispheres.

What you receive

Decimal degrees, degrees-decimal-minutes, degrees-minutes-seconds, copy support, and a CSV with a datum warning.

Calculation method

How coordinate notation is converted

Minutes are divided by 60 and seconds by 3,600 to produce decimal degrees. Output notation reverses that process and carries rounded 60 minutes or seconds into the next whole unit.
