Latitude Longitude Distance Calculator
Find the great-circle distance between two coordinates.
The haversine formula gives the shortest distance over the Earth's surface.
How the Math Works
The Latitude Longitude Distance Calculator uses the Haversine formula to compute the shortest path between two points on a sphere, such as Earth. This formula accounts for the curvature of the Earth by calculating the central angle between two coordinates using their latitudes and longitudes. It involves converting degrees to radians, computing the differences in latitude and longitude, and applying trigonometric functions to determine the great-circle distance. The result is multiplied by Earth's radius (typically 6,371 kilometers) to yield the distance in kilometers or miles, providing a precise measurement over the sphere's surface.
Practical Applications
This calculator is essential for navigation, aviation, and maritime travel, where determining the most efficient route between two locations is critical. Pilots, sailors, and logistics planners use it to estimate fuel consumption, travel time, and optimal flight paths. It also supports geographic research, urban planning, and emergency response by enabling accurate distance calculations for route optimization and resource allocation in real-world scenarios.
Day-to-Day Use
In everyday life, this tool helps travelers compare distances between cities when choosing flights, road trips, or hiking routes. Fitness enthusiasts might use it to estimate walking or cycling distances between landmarks, while students learning geography can visualize global distances. Additionally, it aids in understanding how apps like Google Maps calculate travel times and distances, making abstract geographic concepts tangible and practical for personal decision-making.
Worked example
London to Paris is about 344 km.
FAQ
Is this the driving distance?
No - it's the straight great-circle distance, as the crow flies.
