Convert WGS84, UTM and MGRS coordinates offline with saved points.
Convert WGS84 coordinates offline between decimal degrees, degrees/minutes/seconds (DMS), UTM and MGRS. Enter values manually, review the assumptions and copy the format you need. No GPS or PatchMedia account is required. INCLUDED FREE • Unlimited manual coordinate conversion. • All five MGRS precisions, with the grid cell size stated clearly. • Decimal, DMS, UTM and MGRS input, plus public examples. • Copy each output or share readable coordinate text. • Visible WGS84 datum, UTM hemisphere and metre labels. • Norway and Svalbard special-zone notes where applicable. • Light and dark themes, help and unfinished-input recovery. OPTIONAL LIFETIME PRO A one-time, non-consumable upgrade adds named saved points and notes, searchable conversion history, format presets and local saved-work organization. Export selected records as JSON backup, CSV or readable text through Android’s document picker. Restore this app’s supported JSON backups; CSV and text are export formats. The current local purchase price is shown by Google Play. There is no subscription. If Pro is temporarily unavailable, existing work remains readable, labels and notes editable, deletable and exportable. JSON recovery and applying existing presets remain available. Backups never transfer purchase ownership. LOCAL WORK, EXPLICIT HANDOFFS Entered coordinates and saved work remain in app-private storage during normal use. You choose when to copy, share or export. Exported files are not encrypted by this app, and your selected provider may synchronize them. Android automatic backup and device transfer are disabled, so keep a JSON backup you control before changing devices. Both Free and Pro have no ads or PatchMedia analytics. Google Play processes purchases and may send technical Billing diagnostics. KNOW THE LIMITS WGS84 only, within latitude 80° south to 84° north. No UPS/polar conversion or other datums. Grid precision describes a cell size; it does not improve the accuracy of your source coordinate. Saved results are snapshots of their original inputs. This app does not provide maps, live position, navigation, emergency, targeting, certified survey or cadastral services. By PatchMedia. Support: contact@patch-media.com
