How to use the Distance Calculator
Pick two cities from the dropdowns. The tool calculates the great-circle distance (shortest path on Earth's surface) using the Haversine formula. Flight time is estimated assuming a typical commercial jet cruising speed of 850 km/h — actual flights are 10-20% longer due to jet streams and air traffic routing.
