The oXben Distance Calculator computes the straight-line (as-the-crow-flies) distance between two cities using their geographic coordinates. Select a departure city and a destination city from the dropdowns and the tool instantly returns the distance in both kilometres and miles, along with the approximate flight time and a history of your recent lookups.
The calculator covers hundreds of major cities worldwide. It is useful for rough travel planning, geography quizzes, logistics estimates, and understanding global distances. All calculations use the Haversine formula for great-circle distance and run entirely in the browser.
Is this the driving distance or straight-line distance?
This tool calculates straight-line (geodesic) distance, not road distance. For driving directions use a mapping service such as Google Maps.
How many cities are included?
The database covers several hundred major cities across all continents, with coordinates sourced from publicly available geographic datasets.
