Precision coordinate tools
for technical users
Convert between DD, DMS, UTM, MGRS, and Plus Code instantly. Resolve
UN/LOCODEs to coordinates and timezones.
No ads, no clutter, no sign-up.
Coordinate Converter
Paste any coordinate format - or a UN/LOCODE. The system detects it automatically and converts to every other major format in real time.
- Decimal Degrees (DD)
- Degrees Minutes Seconds (DMS)
- Universal Transverse Mercator (UTM)
- Military Grid Reference (MGRS)
- Google Plus Codes
- UN/LOCODE with enrichment
UN/LOCODE inputs resolve to coordinates and display location name, timezone, UTC offset, and local time. All inputs show nearby UN/LOCODEs by distance. Configurable precision (4–10 decimal places), one-click copy, copy all as plain text or JSON. Keyboard-first with Ctrl+K.
