Calculate Distance Between Latitude and Longitude in Android
Calculating the distance between two points given their latitudes and longitudes is a crucial task in Android app development, especially for location-based services. This calculator and guide will help you understand and perform this calculation accurately.
How to Use This Calculator
- Enter the latitudes and longitudes of the two points in the respective input fields.
- Click the “Calculate” button.
- The distance between the two points will be displayed below the calculator.
Formula & Methodology
The Haversine formula is used to calculate the distance between two points given their latitudes and longitudes. The formula is as follows:
a = sin²(Δlat/2) + cos(lat1) * cos(lat2) * sin²(Δlon/2)
c = 2 * asin(sqrt(a))
Distance = R * c
Where R is the radius of the Earth (approximately 6371 km), Δlat is the difference between the latitudes of the two points, and Δlon is the difference between the longitudes of the two points.

Interactive FAQ
What is the Haversine formula?
The Haversine formula is a formula used in geodesy to calculate the distance between two points on the surface of a sphere given their longitudes and latitudes.
For more information, see the Wikipedia article on the Haversine formula and the USGS page on Earth’s radius.
