Coordinate Converter
Paste a point in whatever notation you have — or tap Use my location — and the same spot comes straight back as decimal degrees, DMS, DDM, UTM, MGRS, a Plus Code and a Geohash, all at once. Copy the one your task needs; the maths never leaves the page.
How to convert your coordinates
- Type or paste a latitude/longitude into the box. You can use decimal degrees (
40.7128, -74.0060), degrees-minutes-seconds (40°42'46"N 74°00'22"W) or degrees-decimal-minutes (40°42.767'N 74°00.360'W). - Or tap Use my location to drop in your current GPS position — handy when you just want to read out where you are in a different format.
- Read off every format at once. Each row has a copy button so you can paste straight into a map, form or report.
- Fine-tune by dragging the map marker, or tapping a new spot — the input and all formats update together.
What each format is for
| Format | Looks like | Best for |
|---|---|---|
| Decimal degrees (DD) | 40.712800, -74.006000 | Apps, URLs, spreadsheets — the default for most software. |
| Degrees-minutes-seconds (DMS) | 40°42'46"N 74°00'22"W | Nautical and aviation charts, traditional map reading. |
| Degrees-decimal-minutes (DDM) | 40°42.767'N 74°00.360'W | GPS units, marine navigation and many handheld receivers. |
| UTM | 18T 583959 4507351 | Surveying and GIS — metres on a flat grid, easy to measure. |
| MGRS | 18T WL 83959 07350 | Military and search-and-rescue grid references. |
| Plus Code (OLC) | 87G7PX7V+4J | A short code for any place, even without a street address. |
| Geohash | dr5regw3p | Databases and indexing — nearby points share a prefix. |
Accuracy, datums and rounding
Every row resolves the same point on Earth, all on the WGS84 datum — the frame GPS and web maps share. Only the notation and rounding differ between rows. Decimal degrees carry six places, a resolution of roughly 11 cm; the grid formats (UTM, MGRS) settle to whole metres. Feed one of these figures into a system tied to a different datum — an older national grid, say — and the same coordinate can land tens of metres off, so confirm what the receiving system expects. To take your own reading first, open what are my coordinates; to measure the line between two fixes, use distance between coordinates.
Privacy
The figures you enter or capture are solved on your device. Use my location requests browser permission and keeps the resulting fix local. Once the page has loaded the converter runs without a network — sound for sensitive coordinates you would rather not type into a search box.
Frequently asked questions
What input formats can I paste?
40.7128, -74.0060), degrees-minutes-seconds (40°42'46"N 74°00'22"W) and degrees-decimal-minutes (40 42.767 N, 74 00.360 W). Hemisphere letters (N/S/E/W) and signed numbers both work, and the comma between latitude and longitude is optional when hemispheres are present.What is the difference between UTM and MGRS?
What is a Plus Code?
87G7PX7V+4J that encodes a small rectangle anywhere on Earth, including places with no street address. It is open and free to use, and works offline once you have the code.
