DMS → WGS 84

Degrees, minutes and seconds to latitude and longitude converter

Convert DMS coordinates to decimal latitude and longitude individually or in batches. See accepted notation, coordinate-order options and rounding notes.

Batch coordinate converter

Enter one DMS coordinate per line as latitude, longitude, including hemisphere letters.

Input example: 51°30′25.92″N, 0°07′39.36″W

0 of 100 coordinates

Results use: latitude, longitude order.

Output example: 51.5072, -0.1276

Numeric coordinates are rounded for display: decimal latitude/longitude to up to 6 decimal places, metre-based coordinates to up to 3, DMS seconds to up to 2, and DDM minutes to up to 4.

About this conversion

This route parses WGS 84 degrees, minutes and seconds with hemisphere letters and returns the same position in decimal degrees.

Frequently asked questions

What input is accepted?

By default, enter the latitude DMS component followed by longitude, using N or S and E or W. Select Reverse coordinate order to enter longitude first. Symbols or ordinary spaces are accepted; minutes and seconds must be below 60.

What output will I receive?

By default, results show WGS 84 latitude first and longitude second in decimal degrees. Select Reverse coordinate order to show longitude first. Displayed decimal places do not add accuracy to the source.

Which axes and units are used?

DMS input and decimal-degree output are angular WGS 84 coordinates. Both default to latitude before longitude, with a separate reverse-order control for each side.

How are precision and datum handled?

This changes notation only, not datum or source accuracy. Decimal-degree results are rounded to at most six decimal places.

Where can I use this coordinate system?

DMS is valid worldwide, including the antimeridian and poles.

What should I check?

  • Check that the selected input order matches each DMS row.
  • Use hemisphere letters that agree with any coordinate signs.
  • Keep minutes and seconds below 60.

Does converting from DMS change the datum?

No. This route converts one WGS 84 notation to another.

Which value appears first?

Latitude appears first in both input and output by default. Either side can be reversed with its coordinate-order control.
