What Does This Tool Do?
You select a “From” city and a “To” city from a dropdown list. The tool uses the geographic coordinates of those cities to compute the great-circle distance—the shortest path over the Earth’s surface—and displays it in miles and kilometers. It does not include actual road or driving distance, which is often longer. Use it to compare flight or “as the crow flies” distances, to gauge scale for a road trip, or to plan multi-city routes. The calculation runs in your browser with no account required.
How to Use It (Step-by-step)
- Choose the starting city in the “From” dropdown.
- Choose the destination city in the “To” dropdown.
- Read the “Distance” result in miles and km.
- Change either city to compare different pairs.
Key Features
- Predefined major cities (e.g. New York, London, Tokyo, Sydney).
- Result in both miles and kilometers.
- Great-circle (straight-line) distance for quick reference.
- No sign-up; runs in the browser.
Use Cases
- Estimating how far two destinations are for a road trip or flight.
- Comparing distances between several city pairs for itinerary planning.
- Understanding scale when reading about a region or route.
- Rough fuel or time estimates when combined with average speed (use our Fuel Cost Calculator for cost).
- Teaching or learning geography with real distances.
FAQ
No. It’s straight-line (great-circle) distance. Driving distance is usually longer; use a map or routing app for that.
The current version uses a fixed list of cities. For other places, you can look up a nearby listed city or use an external map tool.
Travelers use both: miles in the US and UK, kilometers in most other countries. We show both for convenience.
Yes. It’s free and runs in your browser with no account.
