Haversine Flight Distance & Great Circle Calculator
The haversine formula computes the great-circle distance between two points on a sphere given their latitude and longitude. Enter the coordinates below to estimate straight-line travel distance, useful for flights, sailing routes, or long-distance hikes.
About this calculator
Calculate the great-circle distance between two points on Earth using latitude and longitude with the haversine formula.
Frequently Asked Questions
What is the haversine formula?
The haversine formula calculates the shortest distance between two points on a sphere given their latitudes and longitudes, accounting for the Earth's curvature.
Is this the same as actual flight distance?
This gives the great-circle (as-the-crow-flies) distance. Actual flight paths may be longer due to air routes, wind, and airspace restrictions.
Where can I find latitude and longitude for a location?
You can find coordinates using any mapping service by searching for the location and viewing its GPS details.
