As The Crow Flies - Distance Between Random Places on Earth

About This Distance Calculator

As The Crow Flies is a fun and educational tool that shows you the straight-line distance between two random places on Earth. Each time you visit or click "Again", you'll discover a new pair of cities and learn how far apart they are "as the crow flies".

What is "As the Crow Flies" Distance?

The phrase "as the crow flies" refers to the shortest distance between two points, measured in a direct line. Unlike road or flight paths that must navigate around obstacles, this measurement shows the true geographic distance across Earth's surface.

How We Calculate Distance

We use the Haversine formula to calculate the great-circle distance between two points on Earth. This mathematical formula accounts for the curvature of the Earth, giving you an accurate measurement of the shortest path along the planet's surface.

Features

• Random city pairs from around the world
• Accurate distance calculation using the Haversine formula
• Interactive map showing the great circle route
• Estimated travel times by plane, car, and on foot
• Countries crossed along the route

Fun Geography Facts

Did you know that the longest possible distance between two points on Earth is about 20,000 km? That's the distance from one point on the equator to the exact opposite point, passing through the center of the Earth. The circumference of Earth is approximately 40,075 km.
