How It Works
Earthpoint converts between all major WGS84 coordinate systems instantly, with no rounding errors and configurable precision.
Getting Started
Select Input System
Click the tab for the coordinate format you're starting with — UTM, DD, DMS, DDM, or MGRS.
Enter Coordinates
Type your coordinates in the input column. All other columns update in real time.
Paste from Spreadsheet
Copy rows directly from Excel or Google Sheets and paste into any input cell. Multiple rows are populated automatically. Press Ctrl+Z to undo a paste.
View on Map
Hover a row and click the pin icon to see it on an interactive OpenStreetMap.
Batch Import
Upload a CSV or Excel file and map columns to fields. Convert hundreds of points at once.
Export Results
Download your results as CSV or KML for use in GIS software, Google Earth, and more.
Save Projects
Save your entire table state as a named project with an optional project number and name.
Reload & Search Projects
Open any saved project from the Saved Projects page. Search by file name or project number, and export or delete projects.
Output Settings
Customise decimal precision per coordinate system and choose your preferred CSV column layout (separated, combined, or fully merged).
Coordinate Systems
Universal Transverse Mercator (UTM)
A grid-based coordinate system dividing the world into 60 zones. Uses Easting and Northing in meters. Widely used in surveying and military navigation.
32U 698765.123E 5710432.456NDecimal Degrees (DD)
The most common digital format. Latitude and longitude as simple decimal numbers. Positive = North/East, negative = South/West.
51.507400, -0.127800Degrees Minutes Seconds (DMS)
Traditional geographic notation. Each degree is divided into 60 minutes and each minute into 60 seconds.
51° 30' 26.64" N, 0° 7' 40.08" WDegrees Decimal Minutes (DDM)
Hybrid format used in aviation and nautical navigation. Degrees are whole numbers; minutes are expressed as decimals.
51° 30.4440' N, 0° 7.6680' WMilitary Grid Reference System (MGRS)
An alphanumeric grid reference used by NATO military forces. Derived from UTM with letter grid designators for 100km squares.
30U XC 83635 22519UTM Global Zone & Hemisphere
When all your UTM points share the same zone or hemisphere, enable the Global Zone and/or Global Hemisphere toggles. This syncs the value across every row so you only need to enter it once — ideal for batch conversions within a single UTM zone.
Same Zone
Set one UTM zone number (1–60) for all rows. Individual zone fields are hidden when this is active.
Same Hemisphere
Set North or South once for the entire table. Per-row hemisphere inputs are replaced by the global value.
Output Settings
Decimal Precision
Registered users can adjust output precision per coordinate system:
4, 6, or 8 decimal places
8dp ≈ 1mm accuracy
0, 2, or 3 decimal seconds
3dp ≈ sub-millimeter
0, 1, 2, or 3 decimal places
3dp = 1mm resolution
CSV Export Format
Choose how each system is structured in exported CSV files:
UTM — Separated
4 columns: Easting, Northing, Zone, Hemisphere
UTM — Combined with Lat Band
1 column: e.g. 56J 398000.000 5710000.000
DMS — Separated
8 columns: Deg/Min/Sec/Hem for Lat & Lon
DMS — Lat+Lon cols
2 columns: formatted DMS string per axis
DMS — Fully combined
1 column: Lat, Lon as a single string
MGRS — Full / Split
1 column full string, or 4 split columns (GZD, 100k ID, Easting, Northing)
Configure these under Output Settings.
