Latitude + longitude notation converter

Same angles.
A clearer note.

Move one known coordinate pair between signed decimal degrees and degrees, minutes and seconds. Keep the hemisphere, exact angle and display rounding visible. Every calculation runs locally.

Input formatSwitches require valid current inputs. Format-only changes preserve the exact canonical angles; editing an axis establishes a new angle for it.

Latitude · signed degrees−90 through +90. North is positive; south is negative.Longitude · signed degrees−180 through +180. East is positive; west is negative. No automatic wrapping.

Decimal inputs allow up to 12 places, optional DD +/− signs and no commas or exponents. More displayed digits do not establish greater positional accuracy.

One known geographic pair, entered separately. No GPS or geolocation access, maps, coordinate API, file upload, datum or projection transformation, altitude or distance calculation. The example angles do not locate the user or establish a WGS84 reference.

Define the sign.

Positive DD means north or east. In DMS, enter nonnegative components and select N/S or E/W explicitly.

Separate rounding.

Displayed seconds can carry into minutes and degrees. The exact canonical angle stays unchanged during format-only switches.

Keep the provenance.

Local text and CSV include exact rational degrees and the original sign or hemisphere entry, alongside rounded output.
