Longitude and Latitude Distance Calculator Online

1. Single : Calculates the distance between two latitude and longitude coordinates.
2. Batch : Enter two latitude and longitude coordinates per line, and you can enter multiple lines. Batch calculate the distance between a set of latitudes and longitudes.
3. The longitude range of input coordinates is [-180,180] , unit is degree(°). The east longitude is positive and the west longitude is negative. The latitude range of input coordinates is [-90,90] , unit is degree(°). The north latitude is positive and the south latitude is negative.
4. Formula : Choose whether to use the Vincenty formula (ellipsoidal model) or the Haversine formula (spherical model) to calculate the distance between two latitude and longitude.
5. Result Unit : Select the unit of distance, support meter (m), kilometer (km), mile (mi), nautical mile (nMi).
6. Precision : The number of digits reserved after the decimal point, optional, the value range is [0-15] .
7. The Earth radius used for distance calculation is the mean radius with a value of 6371.0087714 km.
8. The Vincenty formula uses an ellipsoid model with high theoretical calculation accuracy.
9. The Haversine formula uses a spherical model, with higher latitudes, greater error.
