Geographical Distance Calculator
Calculate the straight-line (great-circle) distance between two sets of geographical coordinates.
📍 Point A (Start)
🎯 Point B (End)
The Haversine Formula
This tool calculates the shortest distance between two points on the surface of a sphere (the Earth), known as the **great-circle distance**. This is achieved using the **Haversine formula**, which is a widely accepted method for navigation and routing.
Why Use This Tool?
- ✔ **Accuracy:** Calculates the true distance over the curve of the Earth, unlike flat map measurements.
- ✔ **Navigation:** Essential for determining flight paths, shipping routes, and amateur radio range.
- ✔ **Multiple Units:** Provides results in Kilometers, Miles, and Nautical Miles.
- ✔ **Simplicity:** Easily compare distances between major global cities by inputting their coordinates.
Geographical Coordinates
Geographical coordinates use a decimal format:
- **Latitude:** Measures North-South position relative to the equator (0°). Ranges from 90°S (-90) to 90°N (+90).
- **Longitude:** Measures East-West position relative to the Prime Meridian (0°). Ranges from 180°W (-180) to 180°E (+180).
