Great-circle distance
Estimate surface distance using a spherical Earth radius of 6371.0088 km; not a route planner.
Enter latitudes and longitudes in degrees. The tool applies the haversine formula to the shortest surface arc on a sphere, then converts the resulting kilometers to miles.
How to use
- Enter your text, values, or image.
- Adjust the options and run the tool.
- Copy or download your result.
Worked example
Example input
First latitude (degrees): 0 First longitude (degrees): 0 Second latitude (degrees): 0 Second longitude (degrees): 90

}Limitations and details
Uses a spherical approximation rather than an ellipsoid; it does not include roads, terrain, altitude or travel time.
