A Distance Calculator measures the straight-line (air) distance between two locations on Earth. It uses the geographic coordinates (latitude and longitude) of each place and applies the Haversine formula to calculate the great circle distance — the shortest path between two points on a sphere.
Simply type the name of your starting city or location in the 'From' field and your destination in the 'To' field, then click Calculate. The tool returns the distance in kilometers, miles, and nautical miles simultaneously. Adding the country or state name (e.g. 'Paris, France') improves accuracy.
This calculator shows the straight-line air distance (also called great circle distance or 'as the crow flies') between two cities. Actual driving or road distance will typically be longer and depends on available routes, highways, and terrain. For driving directions, a navigation app like Google Maps is recommended.
A kilometer (km) equals 1,000 meters, commonly used worldwide. A mile (mi) equals approximately 1.609 km and is used primarily in the US and UK. A nautical mile (nm) equals approximately 1.852 km and is used in aviation and maritime navigation. All three units are shown simultaneously in the results.
The shortest distance between any two cities on Earth is the great circle distance — the arc of a sphere connecting the two points. This is what our calculator computes using the Haversine formula based on each city's latitude and longitude coordinates.
A mileage calculator estimates the distance between two places measured in miles. It is especially useful for trip planning, fuel cost estimation, and logistics. Our tool functions as a mileage calculator by displaying the result in miles alongside kilometers and nautical miles.
The calculation is based on geocoded coordinates for the city centers or named locations entered. Air distance accuracy is very high using the Haversine formula. However, results represent point-to-point great circle distance, not road distance, so real-world travel distances will differ.
Yes — this calculator works for any two locations worldwide, including cities on different continents. Simply enter the city and country name for each location (e.g. 'Tokyo, Japan' and 'Sydney, Australia') and the tool calculates the international great circle distance.
