常见问题
What is the Haversine formula?
The Haversine formula calculates the great-circle distance between two points on a sphere from their latitudes and longitudes. It accounts for the curvature of the Earth.
How accurate is the result?
The Haversine formula assumes the Earth is a perfect sphere (radius ≈ 6371 km). The actual error is typically less than 0.3% because the Earth is slightly ellipsoidal.
What format should coordinates be in?
Enter decimal degrees (e.g., 55.7558 for latitude, 37.6176 for longitude). Northern latitudes and eastern longitudes are positive; southern and western are negative.
What is the maximum possible distance?
The maximum distance between two points on Earth is about 20,015 km — the distance along a great circle from one point to its antipodal point.
How do I find GPS coordinates?
You can find coordinates using Google Maps (right-click on a point) or from your smartphone's GPS. The first number is latitude, the second is longitude.
