Distance Between Coordinates Calculator (Haversine)
Compute the precise great-circle distance between two geographic points using latitude and longitude. Features batch processing for multiple coordinates and initial bearing calculation.
Point A (Origin)
Point B (Destination)
Batch Processing (Optional)
Paste multiple pairs (Lat, Lon, Lat, Lon) or (Lat, Lon) to (Lat, Lon). One entry per line.
About
Geographic distance calculation differs significantly from Euclidean geometry due to the curvature of the Earth. A straight line on a map (Mercator projection) is rarely the shortest path between two points on a sphere. This tool employs the Haversine formula to compute the Great Circle Distance, which represents the shortest path over the earth's surface.
This utility is essential for developers working with geospatial data, logistics planners optimizing routes, and aviation enthusiasts. It includes a batch processor to handle bulk coordinate arrays and a parser capable of cleaning messy input formats (e.g., degrees/minutes/seconds symbols).
Formulas
The distance (d) is calculated using the Haversine formula, where ฯ is latitude, ฮป is longitude, and R is the Earth's radius.
