Convert between DMS and decimal degrees with strict validation and a clean result card.
Last updated: June 2026 | By Patchworkr Team
DMS to decimal degrees uses DD = D + M/60 + S/3600, with the sign taken from the degree value.
Decimal degrees to DMS splits the absolute value into degrees, minutes, and seconds, then re-applies the sign.
The example matches the default DMS input.
