Free Coordinate Converter Tool (WGS84, UTM, Lambert, XYZ & More)
If you work with maps, GPS data, or geospatial projects, you often need to convert coordinates between different systems. Our free online coordinate converter makes this simple, fast, and accurate.
You can easily convert GPS coordinates (WGS84) into popular projections like UTM, Lambert, Mercator, RGF93, NAD83, NAD27, and more. We are continuously adding new datums and projections based on user requests.
New Feature: Geocentric Cartesian Coordinates (X, Y, Z)
We’ve added support for Geocentric Cartesian coordinates (X, Y, Z) based on user feedback.
How to Use:
- Convert Long, Lat, h → X, Y, Z
- Select WGS84 on the left
- Select WGS84_XYZ (geocentric) on the right (International menu)
- Convert X, Y, Z → Long, Lat, h
- Select WGS84_XYZ (geocentric) on the left
- Select WGS84 on the right
This feature is useful for advanced geospatial calculations, 3D mapping, and scientific applications.
What is a Coordinate Converter?
A coordinate converter allows you to transform geographic coordinates between different geodetic systems and map projections.
For example, you can:
- Convert GPS (WGS84) to UTM zones
- Convert latitude/longitude to Lambert projection
- Transform between NAD83, NAD27, RGF93, and more
This tool is ideal for GIS professionals, engineers, surveyors, and students.
Understanding Key Terms
- X, Y → Plane projection coordinates
- Z / h → Ellipsoid height (altitude)
- Longitude (Long) → East-West position
- Latitude (Lat) → North-South position
- DMS → Degrees, Minutes, Seconds format
How to Convert GPS Coordinates
To convert GPS coordinates:
- Select WGS84 as the input system
- Choose your target system (for example: UTM Zone 10N)
- Enter your coordinates
- Get instant, accurate results
Angle Unit Conversion
You can also convert angle units such as:
- Degrees
- Degrees Minutes Seconds (DMS)
- Gradians
- Radians
This is helpful when working across different mapping standards.
Accuracy and Important Notes
Coordinate transformations can vary in accuracy depending on several factors:
- Regional geodetic systems
- Datum parameters and updates
- Error propagation
- Local mapping standards
Before relying on results, it’s recommended to:
- Verify with known control points
- Cross-check results with other tools
- Ensure compatibility with your project requirements
Like all coordinate conversion tools, results should be used with proper validation.
